# The primary version (e.g. 6.7, 6.6.1) is set in the AC_INIT line
# above.  If this is not a released version, then we will append the
# date to the version number (e.g. 6.7.20070204).  The date is
# constructed by finding the date of the most recent patch in the
# darcs repository.  If this is a source distribution (not a darcs
# checkout), then we ship a file 'VERSION' containing the full version
# when the source distribution was created.

dnl Note OSTYPE: On Cygwin we need to use 'cygpath' to convert
dnl              /cygdrive/c/foo to c:/foo but we must not do that if we
dnl              aren't building using Cygwin (notably msys), because
dnl              cygpath doesn't exist.  It seems that 'bash' sets
dnl              OSTYPE to 'cygwin' or 'msys' respectively, but cygwin's
dnl              'sh' does not.  So we hackily assume that if the shell
dnl              hasn't set it to 'msys' then we must be in Cygwin.
