RE: wrong link command called

[Jonathan Baccash]

No, my PATH is set properly.  As I stated in my first email, the link
command calls the correct link command if you force make to spawn a
shell to do it, i.e. when I try something like "which link && link
/DEBUG $^ /OUT:$@".  The problem is that GNU make uses OpenFile(), which
first looks in the directory where make was begun, BEFORE the path.
This is apparently not how the Cygwin shell lookup works.

If you set and export PATH from within the Makefile does it help/

It is dependent upon the environment in which you operate.  Your issue
is
not make specific it is environment specific.  You may need to change
the
Windows value of PATH in order to have the fact that you have
/cygwin/bin/link and /cygdrive/c/PF/MSVS2003/VC7/BIN/link in PATH.  You
could try renaming /cygwin/bin/link I'm not sure what package that comes
from but some invocation of setup update may cause it to be reinstated.
