# SYNOPSIS
#
#   AX_CHECK_PATHNAME_STYLE_DOS
#
# DESCRIPTION
#
#   Check if host OS uses DOS-style pathnames. This includes the use of
#   drive letters and backslashes. Under DOS, Windows, and OS/2, defines
#   HAVE_PATHNAME_STYLE_DOS and PATH_SEPARATOR to ';'. Otherwise, defines
#   PATH_SEPARATOR to ':'.
#
#   This macro depends on the AC_CANONICAL_HOST.
#
#   Use for enabling code to handle drive letters, backslashes in filenames
#   and semicolons in the PATH.
