Put -D and -I flags into CPPFLAGS rather than into CFLAGS; that should
make them apply to C++ as well as C. That seems to be what the autoconf
documentation suggests:
- Variable: CFLAGS
Debugging and optimization options for the C compiler. If it is not set
in the environment when configure runs, the default value is set when
you call AC_PROG_CC (or empty if you don't). configure uses this
variable when compiling or linking programs to test for C features.
If a compiler option affects only the behavior of the preprocessor
(e.g., -Dname), it should be put into CPPFLAGS instead. If it affects
only the linker (e.g., -Ldirectory), it should be put into LDFLAGS
instead. If it affects only the compiler proper, CFLAGS is the natural
home for it. If an option affects multiple phases of the compiler,
though, matters get tricky. One approach to put such options directly
into CC, e.g., CC='gcc -m64'. Another is to put them into both CPPFLAGS
and LDFLAGS, but not into CFLAGS.
...
- Variable: CPPFLAGS
Preprocessor options for the C, C++, Objective C, and Objective C++
preprocessors and compilers. If it is not set in the environment when
configure runs, the default value is empty. configure uses this variable
when preprocessing or compiling programs to test for C, C++, Objective
C, and Objective C++ features.
This variable's contents should contain options like -I, -D, and -U that
affect only the behavior of the preprocessor. Please see the explanation
of CFLAGS for what you can do if an option affects other phases of the
compiler as well.

For "pcap_findalldevs()", don't assume that just because it's in -lpcap
it's usable - one of the updates to OS X 10.3 updated libpcap to
0.8[.x], so that it had "pcap_findalldevs()", but didn't update
"pcap.h", so it didn't declare "pcap_if_t", so you couldn't actually
*use* it. You can work around that by installing the pcap.h (and
pcap-bpf.h) from the matching tcpdump.org release, but, as even when
that version of OS X is pre-installed rather than being the result of a
Software Update, you still don't get the new "pcap.h" (at least I didn't
get it on my PowerBook with 10.3.4). Therefore, we check whether a
program that calls "pcap_findalldevs()" *and* declares a "pcap_if_t *"
to pass to it can be compiled and linked with -lpcap, and only declare
HAVE_PCAP_FINDALLDEVS if we can.
Also, don't check for the functions added to libpcap after
"pcap_findalldevs()" was added unless we have a usable
"pcap_findalldevs()", as, if not, those functions won't be declared in
"pcap.h" either, so we'll get compiler warnings.

If there's no "zlib.h" header, we won't be using zlib, so don't bother
checking for "gzgets()" in zlib.
If there is a "zlib.h" header, and there is a "gzgets()" in zlib, check
whether we find "gzgets()" in zlib when we link with the GTK+ link
flags, and, if not, fail. People often grab XFree86 source and build
and install it on their systems, and they appear sometimes to
misconfigure XFree86 so that, even on systems with zlib, it assumes
there is no zlib, so the XFree86 build process builds and installs its
own "mini-zlib" in the X11 library directory. The "mini-zlib" lacks
"gzgets()", and that's the zlib with which Ethereal gets linked, so the
build of Ethereal fails.

Put -D and -I flags into CPPFLAGS rather than into CFLAGS; that should
make them apply to C++ as well as C. That seems to be what the autoconf
documentation suggests:
- Variable: CFLAGS
Debugging and optimization options for the C compiler. If it is not set
in the environment when configure runs, the default value is set when
you call AC_PROG_CC (or empty if you don't). configure uses this
variable when compiling or linking programs to test for C features.
If a compiler option affects only the behavior of the preprocessor
(e.g., -Dname), it should be put into CPPFLAGS instead. If it affects
only the linker (e.g., -Ldirectory), it should be put into LDFLAGS
instead. If it affects only the compiler proper, CFLAGS is the natural
home for it. If an option affects multiple phases of the compiler,
though, matters get tricky. One approach to put such options directly
into CC, e.g., CC='gcc -m64'. Another is to put them into both CPPFLAGS
and LDFLAGS, but not into CFLAGS.
...
- Variable: CPPFLAGS
Preprocessor options for the C, C++, Objective C, and Objective C++
preprocessors and compilers. If it is not set in the environment when
configure runs, the default value is empty. configure uses this variable
when preprocessing or compiling programs to test for C, C++, Objective
C, and Objective C++ features.
This variable's contents should contain options like -I, -D, and -U that
affect only the behavior of the preprocessor. Please see the explanation
of CFLAGS for what you can do if an option affects other phases of the
compiler as well.

Put -D and -I flags into CPPFLAGS rather than into CFLAGS; that should
make them apply to C++ as well as C. That seems to be what the autoconf
documentation suggests:
- Variable: CFLAGS
Debugging and optimization options for the C compiler. If it is not set
in the environment when configure runs, the default value is set when
you call AC_PROG_CC (or empty if you don't). configure uses this
variable when compiling or linking programs to test for C features.
If a compiler option affects only the behavior of the preprocessor
(e.g., -Dname), it should be put into CPPFLAGS instead. If it affects
only the linker (e.g., -Ldirectory), it should be put into LDFLAGS
instead. If it affects only the compiler proper, CFLAGS is the natural
home for it. If an option affects multiple phases of the compiler,
though, matters get tricky. One approach to put such options directly
into CC, e.g., CC='gcc -m64'. Another is to put them into both CPPFLAGS
and LDFLAGS, but not into CFLAGS.
...
- Variable: CPPFLAGS
Preprocessor options for the C, C++, Objective C, and Objective C++
preprocessors and compilers. If it is not set in the environment when
configure runs, the default value is empty. configure uses this variable
when preprocessing or compiling programs to test for C, C++, Objective
C, and Objective C++ features.
This variable's contents should contain options like -I, -D, and -U that
affect only the behavior of the preprocessor. Please see the explanation
of CFLAGS for what you can do if an option affects other phases of the
compiler as well.
