Bug#373623: Conflicting CFLAGS in build (-ansi).

[Pat Suwalski]

Package: mesa
Version: 6.4.2-1

The mesa package doesn't compile on Sarge because gcc-3.3.5 gets confused.

debian/configs defines both "-ansi" and "-std=c99" in the 
DEBIAN_COMMON_CFLAGS variable. DEBIAN_COMMON_CXXFLAGS also has "-ansi".

 From the gcc manpage:

	"The -ansi option is equivalent to -std=c89."

The compiler is getting confused. Even if it works in newer GCC, it's 
still not right.

Mesa compiles properly when "-ansi" is removed from DEBIAN_COMMON_CFLAGS 
and DEBIAN_COMMON_CXXFLAGS.
