Hi Mat,

Cc'ing Peter Foley who did the gcc-wrapper.

The SRCDIR looks correct, SRCDIR here specifies the top directory where
the entire source package is located, not it's various subdirectories.

Does the wrapper actually execute the command in that then current
subdirectory?

This error
> cl : Command line error D8003 : missing source filename
is not accidentally caused by the -c option being followed by the
-showIncludes option?

However, what also looks suspicious to me is that the renaming of the
object file does not occur anywhere on that command line, apparently the
target should be

>   CC     liblangtag_la-lt-database.lo
> make[6]: *** [liblangtag_la-lt-database.lo] Error 1

so there should be some -o option followed by the output filename if I'm
not mistaken.

And, last but not least, why does this fail only for Mat?

Seeing wntmsci13.pro in the workdir path suggests this is MSVC 2010,
correct? Maybe that simply works different..
