Gcc3.2 build error on Solaris 10

[Dan Keating]

Hi all,

I'm having problems building gcc3.2 on a solaris 10 system. Gcc2.95.3 builds
fine, but 3.2 and 3.2.3 both fall down with the following error:

/temp/bsm/gcc-sun10/gcc/xgcc -B/temp/bsm/gcc-sun10/gcc/
-B/lang/gcc/3.2/sparc-sun-solaris2.10/bin/
-B/lang/gcc/3.2/sparc-sun-solaris2.10/lib/ -isystem
/lang/gcc/3.2/sparc-sun-solaris2.10/include -DHAVE_CONFIG_H -I.
-I../../../../gcc-3.2/libstdc++-v3/libmath -I.. -g -O2 -c
../../../../gcc-3.2/libstdc++-v3/libmath/signbit.c -o signbit.o
In file included from ../../../../gcc-3.2/libstdc++-v3/libmath/signbit.c:32:
../../../../gcc-3.2/libstdc++-v3/libmath/mathconf.h:84: conflicting types
for `nan'
/usr/include/iso/math_c99.h:145: previous declaration of `nan'

Configure is being run with parameters "--enable-languages=c++
--disable-shared".

Hopefully there's someone who can see a cause for this.

Regards,

Dan
