Ran across a little gotcha while porting to FreeBSD 2.2.2 where the
didn't have the #ifdef __FreeBSD__ shown below but needed it in order
to get a definition of NGROUPS.
Take out my #include <sys/param.h> and get:
/usr/include/sys/ucred.h:47: `NGROUPS' undeclared here (not in a function)
This mess starts in <sys/mount.h>
Am wondering if the include tree is supposed to include other include
files when making references to external items? Or am I supposed to hunt
them down and include them all myself?
This is the really tough demo program:
#include <stdio.h>
#include <sys/types.h>
#ifdef __FreeBSD__
#include <sys/param.h>
#endif
#include <sys/mount.h>
void main (void) {
printf ("Hello World!\n");
}
