We don't support the use of Cygwin tools to build Base on the win32-x86, 
win32-x86-mingw and windows-x64 targets; you need versions of Make and Perl 
that understand the windows paths for those targets.  If you mix the two you 
just end up with the kinds of problems that you describe above, which neither 
Janet nor I have the time or inclination to try and fix right now.

When building for the Windows API (using either the MSVC++ or MinGW compilers) 
I use the MinGW version of GNUMake and a Perl from ActiveState, although there 
may be alternatives to them.  When building for Cygwin I use the versions of 
Make and Perl that come with Cygwin.  Note that R3.14.12 will support building 
shared libraries on Cygwin 1.7 (using gcc-3, not gcc-4), although that still 
doesn't work on Cygwin 1.5.
