One solution would be to install Cygwin's gettext package, so that 
Cygwin's gettext.sh precedes MinGW's in your path.  (Note that git 
doesn't require gettext; it's not needed because git-sh-i18n provides a 
definition of eval_gettext on systems that don't have it.

In general, however, it seems to me that you're asking for trouble by 
having MinGW binaries in your path while working in Cygwin.
