Errors Compiling GCC 3.2.2 on Fedora Core4

Edit the file include/obstack.h in the gcc-3.2.2 source package. Go to 
line 423 and change it from:
*((void **)__o->next_free)++ = ((void *)datum); \
to:
*((void **)__o->next_free) = ((void *)datum); \
and add the line
__o->next_free += sizeof(void *); \
immediately beneath.

Don't forget the "\" at the ends of the lines after the ";". They are 
part of the code. I did this on FC4 after having the exact same 
problems. Everything compiled and installed fine after that. This patch 
comes from Adrian Reber
