#1257 — conflicting types for `openpty'

I am trying to build openssh 6.3p1

[U:\ports\ssh\openssh-6.3p1-os2]make
(cd openbsd-compat && make.exe)
make.exe[1]: Entering directory  
`U:/ports/ssh/openssh-6.3p1-os2/openbsd-compat'

bsd-openpty.c:79: error: conflicting types for `openpty'

The above is what has got me puzzled.

bsd-openpty.c
int
openpty(int *amaster, int *aslave, char *name, struct termios *termp,
   struct winsize *winp)

openbsd-compat.h

int openpty(int *, int *, char *, struct termios *, struct winsize *);

How do they differ?

Can I persuade gcc to give more info?

TIA

Have you updated to the layest 4.4.6 version of GCC? If not you should 
as it seems to fix this kind of bug

No - Using Paul's build system but still on 335. Will try a later 
version. Ta.

To me it sounds like either "struct termios" or "struct winsize" is not 
defined anywhere. That in turn sounds like some include file is missing 
or not properly included.

Got it in one - the former. This code as *so* many ifdefs it's very 
hard to figure out.
