A few additional questions, then:

Do you use gnu-style configured projects (autoconf, automake, libtool,
all that?) -- or some other build framework?

Do you use cygwin's make (which version?), mingw32-make, or perhaps a
cygwin build of msys's csmake/cpmake?

Do you use gcc's -M* options for generating dependencies -- with
mingw-gcc, these rules will be in dos format and cygwin-make-3.81
doesn't grok them?

What about creating static libraries? If you use mingw's ar.exe, do you
use explicit `cygpath` rules to convert unix paths to the DOS paths that
version of ar can understand, or some other technique?

For a hint about why I started this thread, and why I am asking these
questions, see
http://lists.gnu.org/archive/html/libtool-patches/2009-01/msg00163.html
-- especially my failures with

$ export PATH="/c/MinGW/bin:$PATH"
$ ../libtool/configure --build=i686-pc-cygwin --host=mingw32

This led to a suggestion that "--build=cygwin --host=mingw32" should
always be interpreted as: mingw32-gcc is a cygwin-hosted cross compiler,
NOT the native MinGW-project supported gcc (and if it IS the native
MinGW one, expect breakage). I'm not sure such a sweeping statement is
accurate, or wise -- will that assumption break people's exising
(working) setups?
