# acx_check_pathname_style

## Synopsis

`ACX_CHECK_PATHNAME_STYLE_DOS`

## Version

1.1.1.1 (2001/07/26) Miscellaneous @ ac-archive-0.5.32

## Author

Mark Elbrecht <snowball3@bigfoot.com>

## 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.
