Re: Wine & Boehm garbage collector

-lntdll.dll and -lpthreads were left here from another makefile I've got.
I've removed them but it didn't help.  Here is the usual backtrace from gdb:

Apparently, the problem lies in Boehm GC, but before mailing Hans Boehm
about this (he can probably provide limited support only), I'd like to hear
about the people that knows about the internals of Wine.

You should remove -lntdll and -lpthread, it will probably help. If it
doesn't please post a gdb backtrace of the crash.
