Yes, it is.  In CVS HEAD, it's a dlpreloaded (static) module.

Hmm.  We changed the '-Wl,$lib' specifically for MSYS, because we need
the shell to do the path conversion to w32 paths here.  We could use
'-Xlinker --enable-auto-image-base' as well, I guess, for consistency,
but then again all linker flags passed by the user will have '-Wl,'
prefixed, so that would still be inconsistent.  OTOH, changing all to
'-Xlinker' uses a tiny bit more command line length, a scarce resource
on w32.  We could also separate mingw from cygwin setting here..

Shrug.  I don't know.  What do you like best?

(Some patches for the actual bugs coming up in another mail..)

Cheers,
