gen-introspect: pretend to be lint (1.44 KB, patch)
2014-01-25 06:57 UTC, Allison Karlitskaya (desrt) 		committed Details | Review

Description Allison Karlitskaya (desrt) 2014-01-25 06:57:40 UTC 
Some system headers (notably <stdarg.h> on FreeBSD) get upset when they
see an unexpected compiler.  We go out of our way to pass -U__GNUC__ to
cpp from the scanner code during gen-introspect and this is causing
problems.

As a workaround, we can pretend to be lint, which fixes the issue at
least for FreeBSD.

http://fxr.watson.org/fxr/source/x86/include/stdarg.h is the file in question, fwiw.

Note near the bottom:

   73 #else
   74 #error this file needs to be ported to your compiler
   75 #endif

Thanks for the patch. I don't have a FreeBSD system around but this looks fine to me.
