OK, here's some help. I suppose I dare call myself a programmer :), even
though I haven't tried creating make from it's sources...
In vpath.c lines 103-112 the CygWin specific path conversion is taken
care of in the VPATH variable case.
In the GPATH variable case (line 138-154), it looks like GPATH is not
converted either. This would need some testing, but I suppose GPATH is
hardly a regularly used feature...
Copying lines 101-114 after line 146 should take care of that omission;
the variable 'posixp' has been defines and used previously, but should
still be in scope (lines 64-66), so it may be doubly used (unclean, but
workable).
The vpath directive is processed somwhere else. The only occurrence of
the function 'construct_vpath_list' outside of vpath.c (and make.h for a
prototype) is read.c
In read.c lines 637-656, the directive is processed. And, alas, no
CygWin processing of DOS-like paths there.
Copying the same lines from vpath.c into read.c after line 652 might be
all that's needed, but without actually doing the work+test, it's hard
to tell whether everything is in scope. Be sure to define a variable
'posixp' in this case, however.
If I find a few free minutes, I'll continue from here, but maybe this is
enough input for you already.
HTH,
Johan
