build fails on OSX 10.6 (snow leopard)

[Beef]

sh make.sh on the current latest cvs revision returns an error on the backtrace.c compilation with gcc i686-apple-darwin10-gcc-4.2.1.
I am working on the latest beta version of Snow Leopard OSX (June 8th).

The current working revision for backtrace.c is 1.45

I tried adding the -D_XOPEN_SOURCE, -D_XOPEN_SOURCE=600 and -m32 flags to the CFLAGS

-D_XOPEN_SOURCE changes nothing to the above error.

-D_XOPEN_SOURCE=600 changes the output to:

This blog entry might contain relevant information for this bug.

[Cyrus Harmon (ch-launchpad)]

So there are a few problems:

1. #include <ucontext.h> should go away
2. need -arch i386 in Config.x86-darwin

these are fixed in the patch.

also, the following problems still exist:

3. build failures in sb-posix
4. sb-bsd-socket memory fault errors when calling sb-bsd-sockets:get-address-info

[Cyrus Harmon (ch-launchpad)]

Here's a backtrace for the sb-bsd-socket:get-address-info error. perhaps this should be moved to its own bug.

debugger invoked on a SB-SYS:MEMORY-FAULT-ERROR in thread #<THREAD "initial thread" RUNNING {119D1CA9}>:
  Unhandled memory fault at #xB.

Type HELP for debugger help, or (SB-EXT:QUIT) to exit from SBCL.

restarts (invokable by number or by possibly-abbreviated name):
  0: [ABORT] Exit debugger, returning to top level.

An initial fix is in 1.0.31.2, but the sb-posix test failures are still troubling, but this has been moved to bug 421779: https://bugs.launchpad.net/sbcl/+bug/421779
