+Cygwin GCC
+Ethereal can entirely be built with cygwin GCC. However the built binaries will
+only run in a cygwin environment, so they are not standalone Win32 applications.
+It is however not excluded that native Win32 code can be compiled on cygwin GCC
+but you then have to use -mms-bitfields as a strict minimum and probably
+-mno-cygwin or a similar compiler flag too.
