FYI: PATH_SEP

[Akim Demaille]

Index: ChangeLog
from  Akim Demaille  <address@hidden>
        * acgeneral.m4 (_AC_INIT_PREPARE_FS_SEPARATORS): Use `.;.' instead
        of `.;`pwd`': if pwd is c:/foo, we might walk through `.:c'
        (fails), and then `/foo' which might succeed, resulting in
        believing `;' is the right path separator.
