Yes, it's commented out in tests/tests.am, so it should probably also be
taken out of Makefile.direct or added to EXTRA_DIST.

However, it appears to me that GC_generate_random_backtrace is only
emitted if KEEP_BACK_PTRS is defined, which means when configured with
--enable-gc-debug, so is it possible this issue was not Mac OS X 10.3
specific?  The attached patch makes the tests/trace_test.c test
conditioned on --enable-gc-debug.  Can someone test on Mac OS X 10.3?

Makefile is created from Makefile.in by configure.  I contains
substitutions and some conditional sections which are only known after
configure is run, so Makefile should not end up in the tarball.

It's usually not needed by end users, but might be used in some cases if
e.g.  patches are applied after extracting the tarball.  Nevertheless
this is mostly equivalent to "autoreconf -vif", so I think it could be
removed completely.  Before doing so, I'd suggest also removing
"libtool.m4", since it's outdated and cause a lot of noise on newer

The problem is rather its presence in the tarball.  The function of this
file is to hold information about the local installation.  configure
substitutes some installation directories into it.  So, I don't think it
makes sense to distribute it.  This change is include in the attachment.
