[Mono-list] Mono builds for Mac OS X

[Ryan Wilhm]

Thanks, Jeff! I pulled down a snapshot of Mono last night from CVS and
managed to get it to build. Sort of. The major caveat is that, in addition
to not supporting Pthread recursive mutexes, it also doesn't support
read/write locks. I checked out Apple's developer site and found a bugfix
request that details the functionality missing from the Pthread OpenGroup
spec in OS X:

http://www.opensource.apple.com/bugs/X/Libraries/2686231.html

To get things to build in the interim, I just wrote stubs for the methods
that io-layer/events.c calls. (So in other words, don't have much confidence
that the build will work as expected... :) I'm going to be gone on vacation
for a week starting tomorrow, but I'd be happy to give an implementation a
shot when I get back next week.

Everything else was just build massaging... Off the top of my head:

- I set configure.in to target the ppc arch for powerpc-*-darwin*
- For any problematic header dependencies, I just used #if(n)def
__APPLE__/#endif to resolve
- I did end up removing EDOTDOT and ENOMEDIUM
- I ended up needing to manually compiling monoberg.c... I needed to add the
-no-cpp-precomp and a library include flag that wasn't carried forward
during Makefile generation
- I also added the empty read/write lock stub file into the io-layer
Makefile.am and Makefile.in files so I didn't have to hand crank the
Makefile every time might need to reconfigure...

That's about it...

Thanks again for the help!
Ryan
