ENOTSUP trouble in smbd for Samba 3.0.3 under OpenBSD

[Joe]

Folks:
I am having problems compiling the new Samba 3.0.3 on OpenBSD 3.4. The 
problem I get is

Compiling smbd/trans2.c
smbd/trans2.c: In function `set_ea':
smbd/trans2.c:398: `ENOTSUP' undeclared (first use in this function)
smbd/trans2.c:398: (Each undeclared identifier is reported only once
smbd/trans2.c:398: for each function it appears in.)
*** Error code 1

So is ENOTSUP needed? I see that it is used in a few parts of smbd, but 
this error is not defined for this OS.

Thanks
Joe
