#
# Install Preprocessor for the gnuwin "make install" command.
#
# Purpose: 
#   Automatically add the suffix .exe to filenames that require it
#
# To use:
#   Copy this file earlier in the path than the default install.exe
#   It is recommended that the original install.exe be renamed 
#   cyg_install.exe as otherwise some configure programs may fail
#   to find this install script
#
# Note:
#   No warranty implicit or explicit is given.
#   You may copy, distribute and use as you see fit.
#   USE AT YOU OWN RISK.

#   changed ginstall to cyg_install, because some packages are looking
#   for ginstall

#   "I seem to remember earnie's script gave trouble (in X11 or lesstif
#    make install) when both <exec.exe> and <exec> are present
#    simultaneously). The attached helped."

#    Modify logic to work when several files are installed in a directory,
#    some with the .exe extension and others without.
#    Issue warning in case of ambiguity
#    Search for an appropriate install.exe program
