I'm surprised no one has jumped in here and told me how wrong I was
about how exactly gmarshal.h, etc. are generated :) I got some similar
problems running 'make check' so I decided to take a closer look.

gobject/glib-genmarshal is a wrapper script that calls
gobject/.libs/glib-genmarshal.exe, setting up the correct environment,
etc. gobject/glib-genmarshal.exe is a wrapper executable that calls
gobject/glib-genmarshal; the wrapper exe calls the wrapper script that
calls the actual exe. This is all set up by libtool.

Cygwin calls the wrapper executable just fine, but something is wrong
with the wrapper. In fact I don't think any of the wrapper exes are
working correctly. Each wrapper throws this warning on compilation:

creating glib-genmarshal.exe
.libs/lt-glib-genmarshal.c: In function `main':
.libs/lt-glib-genmarshal.c:79: warning: passing arg 2 of `execv' from 
incompatible pointer type

When the wrapper exe is run, it emits no output and returns an exit
value of 0, silently failing. Running the wrapper script directly works 
fine, so the problem must be with the wrapper exe.

Since this appears to be a problem with libtool, I won't bother the 
folks here with more emails about this. This message is for 
completeness/historical purposes :)
