Bug 19447

Summary: ALIGN macro undefined in /usr/include/sys/socket.h
Product: Base System Reporter: john <john>
Component: miscAssignee: freebsd-bugs (Nobody) <bugs>

Description john 2000-06-22 22:30:00 UTC 
Programs using the CMSG_DATA (and others) in /usr/include/sys/socket.h
will not link/load because the ALIGN macro is not defined, and the
compiler thinks it should be a function that should be resolved.
I think that the definition
of the ALIGN macro is in /usr/include/machine/param.h.  At least, 
my program works when I include it before sys/socket.h.   I think that
any include file that uses the ALIGN macro should define it itself, or
include machine/param.h.

Fix: 

Include machine/param.h in sys/socket.h
How-To-Repeat: Compile srfd.c from the lam-6.3.2 (an MPI implementation) and look at
the symbols in srfd.o, or the assembler output.  They both include
a call to ALIGN, which should have been a macro.
