I've just installed gcc and am trying to
compile various X programs.  Typedefs in include files
do not seem to be recognized across the different files.
The sample program below compiles fine with the Mips compiler.

Can anyone explain this?

Decstation 5000/133, Ultrix 4.2a

sample source code

#include <X11/Xlib.h>
#include <X11/Xutil.h>
#include <X11/Xos.h>
#include <X11/Xatom.h>
#include <stdio.h>

void main()
{
printf("hello, world\n");
}


compile line:

gcc test.c

standard out:

(XSizeHints is typedeffed in Xutil.h)

Thanks in advance.
