Subject: [PATCH 2/5] AC_SITE_LOAD: Convert '\' in PATH to '/' on OS/2

echo of some shells such as pdksh recognizes '\' as an escape
character. So when echoing a path, the result can be corrupted. For
examples, echo x:\usr\bin will be x:\usin.

* lib/autoconf/general.m4 (AC_SITE_LOAD): Convert '\' in PATH to '/'
on OS/2.
