Apparently, not all the time... In automake 1.4a, a script (depcomp) is used
to generate dependencies while also compiling the relevant file; it gets
invoked like this:

.c.o:
    source='$<' object='$@' libtool=no \
    depfile='$(DEPDIR)/$*.Po' tmpdepfile='$(DEPDIR)/$*.TPo' \
    $(CCDEPMODE) $(depcomp) \
    $(COMPILE) -c -o $@ `test -f $< || echo '$(srcdir)/'`$<

with depcomp = $(SHELL) $(srcdir)/depcomp

With the DJGPP port of make, this does not work (the script never sees the
variables). As a workaround in my port (still under development, although I
may release it soon), I enclosed the entire statement in $(SHELL) -c
"<statement here>". This did work (although makefiles using quotes in their
compilation switches now need patching). I'm at a loss as to why this is; if
the same method of invocation is used in a script in bash, it works fine. So
my guess is that it's somehow make's fault.
Any thoughts are appreciated (especially helpful ones :) ).
