Serious compiler problem

[Sebastian Lövdahl <sebastian.lovdahl@pp.inet.fi>]

Hello! I have a very big problem with GCC (maybe this is wrong thread, 
but maybe it isn't GCC related at all). When I try to compile a specific 
file, GCC gives me this:

In file included from globals.h:11,
                from main.c:19:
/usr/lib/gcc-lib/i486-linux/3.3.4/include/stddef.h:151: error: syntax 
error before "typedef"

I have *no* clue why this happened, I just edited the file (main.c), 
saved it, and tried to compile again, and it suddenly gave me this. It's 
not the first time, it happened on another machine too (completly 
different). All help is appreciated*.
