This is exactly what we do -- I don't see anyway around this. It is
certainly much better than trying to maintain two makefiles -- one for
UNIX (ie, GNU make) and one for Windows (ie, Microsoft nmake).

Your "problem" is due to non-Cygwin apps (eg, cl) do not understand
Cygwin constructs such as mount points, symlinks, etc. The way to
map back and forth is cygpath.

My guess would be that e is actually trying to open
c:\usr\include\stdio.h
and not
c:\cygwin\usr\usr\include\stdio.h
This is because the Win32 CreateFile and open *can* deal with forward
slashes but will use the current drive letter for absolute paths if
none is supplied.
I refer you to the "Mapping path names" section of the Cygwin User's
Guide:

for more information.
