That would normally be fine if I was was using Cygwin only, but since my
Makefiles are used in projects built with both RedHat linux and Cygwin, this
new change to `cp.exe' forces me to have to modify all my Makefiles.
Example, I now either need to maintain two makefiles for each project, or
add a conditional expression to all my Makefiles:
BIN= foo
ifeq ($(TERM), cygwin)
BIN:=$(BIN).exe
endif
It's no big deal, but after updating to the newest Cygwin release and
discovering my projects no longer installed because of the new `cp.exe'
seemed like a bug.
