[Mono-list] Configuration problem in mono-0.20 (windows/cygwin)

Okay, I cannot make mono pickup the libgc.  I compiled gc6.1 after a
"configure --prefix=/usr" and make and installation seemed have to
worked.  Still, mono's configure is complaining.

  From the config.log file (please remember, I'm no Unix programmer, I
don't understand all that configure/automake magic) it looks like

configure:8790: checking for GC_malloc in -lgc
configure:8823: gcc -mno-cygwin -o conftest.exe -g -Wall -Wunused
-Wmissing-prot
otypes -Wmissing-declarations -Wstrict-prototypes  -Wmissing-prototypes
-Wnested
-externs -Wpointer-arith -Wno-cast-qual -Wcast-align -Wwrite-strings
-DGC_WIN32
_THREADS -DWIN32_THREADS  conftest.c -lgc   >&5
configure:8805: warning: function declaration isn't a prototype
configure:8814: warning: function declaration isn't a prototype
/usr/lib/gcc-lib/i686-pc-mingw32/3.2/../../../libgc.a(malloc.o)(.text+0x338): 

In
   function `GC_generic_malloc':
/usr/local/mono/gc6.1/malloc.c:189: undefined reference to
`pthread_mutex_lock'

the test program, configure is compiling to check for libgc doesn't work
because the mingw version of gcc is missing some pthread (portable
threads?) library.  Is this a correct observation?  Does this mean, I
didn't compile the libgc stuff correctly?

I /think/ I heard somewhere that mingw has still problems this threads.
   So perhaps this is a problem.  However, there're some win32 specific
files in the distribution perhaps it just didn't know that I wanted a
mingw version of libgc.

If I compare the configure outputs of mono and gc, mono said "checking
for gcc... gcc -mno-cygwin" while gc said "checking for gcc... gcc"

Still, it looks like I'm on the wrong way here, from a posting to
mono-list in November I guess, you need a special build libgc DLL for
windows build with VC++.
