[9fans] u9fs

[David Swasey <swasey@cs.cmu.edu>]

Thanks for srvssh.  Here are the changes I made to get u9fs running on
a SunOS 5.5.1 machine.  -dave

1. A comment:

diff /sys/src/cmd/unix/u9fs/makefile u9fs-new/makefile
5a6,10
> # SunOS
> #
> # SunOS 5.5.1 does not provide inttypes.h; add -Isunos to CFLAGS and change
> # CC and LD to gcc.  Add -lsocket, -lnsl to LDFLAGS.
> #

2. Magic to get timeval defined:

diff /sys/src/cmd/unix/u9fs/plan9.h u9fs-new/plan9.h
5a6,9
> #ifdef sun	/* sparc and __svr4__ are also defined on the offending machine */
> #define __EXTENSIONS__	1	/* for struct timeval */
> #endif
>

3. A version of inttypes.h:

cat u9fs-new/sunos/inttypes.h
/* inttypes.h for SunOS cuff.link.cs.cmu.edu 5.5.1 Generic_103640-29 sun4u sparc SUNW,Ultra-Enterprise */
