I wrote a program which used to compile in January, but since I upgraded
to 1.4U/i386, gives me errors, which you can see for yourself by trying
to compile (cf netintro(4)):

#include <sys/socket.h>
int main(){return 0;}

In file included from socket.c:1:
/usr/include/sys/socket.h:182: syntax error before `u_char'
...

So something changed, but what?

Cheers,

Patrick
