make support for MSDOS paths under Cygwin, wouldn't it? On which Windows
filesystems will this be useful? In other words, where might one see a
directory named "c:" on a Windows box?
Cygwin is a POSIX emulation layer in the first place. That's what we
are committed to in the first place. Why would you want to use Win32
paths in a POSIX environment, except as parameter to native Win32 tools?
[RGW] This is exactly what I want it for. Thing is, I don't want to
know ahead of time whether the tool is Cygwin or not. I'm counting on a
small amount of interoperability. More below...
For dependency tracking in make there's no good reason to use the Win32
[RGW] I respect your opinion. Let me offer mine: I think several
people have offered good reasons before on this list. Our opinions
aside: the reasons offered were good enough for the developers of make
to offer this functionality in the mainline.
You can just as well use the POSIX equivalent. If you have to
convert between paths, there's the cygpath tool.
[RGW] Yes, such a beast would be possible to construct, but it would be
horribly inefficient. I'd be wrapping every file parameter to every
command with a call to cygpath. It may be hard for you to imagine why
I'd object to this, though, so here's some background: our make system
is quite large, and much the content of the makefiles is
auto-generated. We use it to compile or cross-compile some 30 flavors
of our product, using a fairly even mixture of Windows and Cygwin
tools. The makefile generators are of the same even mix (e.g. we use
compilers to generate .dep files).
The exact same make system is used to compile and cross compile on
Linux, MacOS, and NetBSD. The system works very well, with very few
complaints from my team, our customers, and others who have used it.
One of the most often heard complaints is that it's slow on Cygwin
(because of the cost of exec).
