This patch fixes bootstrap failure in ligfortran/instrisics/c99_functions.c for
mips-sgi-irix6.5.
This patch applies cleanly to 4.1 and mainline.
It's similiar as http://gcc.gnu.org/ml/gcc-patches/2005-12/msg01578.html
Patch applied, bootstrap finished successfully for 4.1 svn revision 110639.
Testsuite in progress.
There is one open question. Is the "#ifdef __sgi__" the right way to
distinguish between IRIX and other mips systems?
I ask for comments.
Best regards
Rainer
