Hello,

When compiling gcc 4.3.1 on sun Solaris I get the following error:

---------------------------------------

Of course gmp.h is there - the blimey "xgcc" compiler does not look at  
the right place:

---------------------------------------
> la /opt/gnat/gcc/include/gmp.h
-rw-r--r-- 1 xxxx xxx 81K 2008-06-18 10:39 /opt/gnat/gcc/include/gmp.h
---------------------------------------

And ignores any helpful hints:

---------------------------------------
> grep CFLAGS /work/BUILD/GCC/ultrasparc-sun-solaris2.10/config.log
ac_cv_env_CFLAGS_set='set'
ac_cv_env_CFLAGS_value='-B /opt/gnat/gcc/include'
CFLAGS='-B /opt/gnat/gcc/include'
CFLAGS_FOR_BUILD='-B /opt/gnat/gcc/include'
DEBUG_PREFIX_CFLAGS_FOR_TARGET=''
SYSROOT_CFLAGS_FOR_TARGET=''
---------------------------------------

Any ideas?
