duke@1: # WARNING: This is extremely touch stuff, between CYGWIN vs. MKS and all
duke@1: #          variations of MKS and CYGWIN releases, and 32bit vs 64bit,
duke@1: #          this file can give you nightmares.
duke@1: #
duke@1: # Notes:
duke@1: #   Keep all paths in the windows "mixed" style except CYGWIN UNXIXCOMMAND_PATH.
duke@1: #   Use of PrefixPath is critical, some variables must end with / (see NOTE).
duke@1: #   Use of quotes is critical due to possible spaces in paths coming from
duke@1: #     the environment variables, be careful.
duke@1: #   First convert \ to / with subst, keep it quoted due to blanks, then
duke@1: #     use cygpath -s or dosname -s to get the short non-blank name.
duke@1: #   If the MKS is old and doesn't have a dosname -s, you will be forced
duke@1: #     to set ALT variables with the short non-space directory names.
duke@1: #     If dosname doesn't appear to work, we won't use it.
duke@1: #     The dosname utility also wants to accept stdin if it is not supplied
duke@1: #     any path on the command line, this is really dangerous when using
duke@1: #     make variables that can easily become empty, so I use:
duke@1: #        echo $1 | dosname -s     instead of    dosname -s $1
duke@1: #     to prevent dosname from hanging up the make process when $1 is empty.
duke@1: #     The cygpath utility does not have this problem.
duke@1: #   The ALT values should never really have spaces or use \.
duke@1: #   Suspect these environment variables to have spaces and/or \ characters:
duke@1: #     SYSTEMROOT, SystemRoot, WINDIR, windir, PROGRAMFILES, ProgramFiles,
duke@1: #     MSTOOLS, Mstools, MSSDK, MSSdk, VC71COMNTOOLS, 
duke@1: #     MSVCDIR, MSVCDir.
duke@1: #     So use $(subst \,/,) on them first adding quotes and placing them in
duke@1: #         their own variable assigned with :=, then use FullPath.
