This reverts commit f6b8bc39c6.
Reason for revert: prior to 4.6 or so, the pragmas didn't work as well,
e.g. they couldn't be used inside a function; we depend on them being
usable within a function.

This reverts commit 051efd105a.
Reason for revert: The Clang on the macOS buildbot is 3.1, so it should
have been using the _Pragmas; perhaps it "supports" them but they don't
actually *work*, or perhaps something else is wrong.

This should test whether the macOS buildbot Clang really *does* support
them, in which case we should use them, or not.

Apparently, some versions of Bison also generate global generations of
yylval, or its appropriately-prefixed equivalent, in pure parsers.
Suppress -Wshadow in Bison-generated code as well as Berkeley
YACC-generated code.

Hopefully this filters out stuff about which we can't do very much
(other than send off a Flex fix and wait for it to be accepted and end
up in a WinFlexBison package), making it easier to find the stuff about
which we *can* directly do something (i.e., problems in code *we* wrote).

Berkeley YACC generates a global declaration of yylval, or the
appropriately prefixed version of yylval, in the .h file, *even though
it's been told to generate a pure parser, meaning it doesn't have any
global variables*. Bison doesn't do this.
That causes a warning due to the local declaration in the parser
shadowing the global declaration.
So, if this is Berkeley YACC, and we have _Pragma, and have pragmas to
suppress diagnostics, we use it to turn off -Wshadow warnings.

Add warning C4267 (size_t to int conversion) with MSVC to DIAG_OFF_FLEX.
Addd -Wshorten-64-to-32 with Clang and GCC to DIAG_OFF_FLEX.
Don't explicitly use #pragma to turn off warnings; use DIAG_OFF_FLEX for
all of them.
If we use DIAG_OFF_FLEX, use DIAG_ON_FLEX, even if we have no section of
entirely included code at the end.

DIAG_OFF_FLEX turns off all warnings that we want to disable for
Flex-generated code due to some versions of Flex generating code that
triggers those warnings.
DIAG_ON_FLEX restores those warnings, so we do the checks for code that
*we* wrote.
Use them in .l files.

Avoid anachronisms, however; there was no "macOS 10.0" or even "OS X
10.0", for example. It was "Mac OS X" until 10.8 (although 10.7 was
sometimes called "OS X" and sometimes called "Mac OS X"), and it was "OS
