Solaris 9/x86 bootstrap was broken after the cxx-conversion merge:
In file included from /vol/gcc/src/hg/trunk/local/gcc/gengtype.c:957:
/vol/gcc/src/hg/trunk/local/gcc/rtl.def:347: error: expected identifier before n
umeric constant
/vol/gcc/src/hg/trunk/local/gcc/rtl.def:347: error: expected '}' before numeric
constant
This happens since g++, unlike gcc, defines __EXTENSIONS__, which
exposes the equivalent of
#define PC 14
Initially I tried to avoid this by having gengtype.c include rtl.h,
which already has the #undef, but this produced so much fallout that I
decided it's better to just replicate it here.
The patch allowed an i386-pc-solaris2.9 bootstrap to finish. I think
this counts as obvious unless someone prefers the rtl.h route
nonetheless.
Ok for mainline?
