libtool: Cygwin/Windows File Name Conversion

1 ............................................
1 
1 Cygwin provides a Unix emulation environment for Windows.  As part of
1 that emulation, it provides a file system mapping that presents the
1 Windows file system in a Unix-compatible manner.  Cygwin also provides a
1 utility 'cygpath' that can be used to convert file names and paths
1 between the two representations.  In a correctly configured Cygwin
1 installation, 'cygpath' is always present, and is in the 'PATH'.
1 
1    Libtool uses 'cygpath' to convert from Cygwin (Unix-style) file names
1 and paths to Windows format when the build platform is Cygwin and the
1 host platform is MinGW.
1 
1    When the host platform is Cygwin, but the build platform is MSYS or
1 some Unix system, libtool also uses 'cygpath' to convert from Windows to
1 Cygwin format (after first converting from the build platform format to
DONTPRINTYET 1 Windows format; ⇒Native MinGW File Name Conversion, and *note1DONTPRINTYET 1 Windows format; ⇒Native MinGW File Name Conversion, and ⇒
 Unix/Windows File Name Conversion.)  Because the build platform is not
1 Cygwin, 'cygpath' is not (and should not be) in the 'PATH'.  Therefore,
1 in this configuration the environment variable 'LT_CYGPATH' is required.
