    -  foreach my $dir (reverse split /:/, $ENV{"ACLOCAL_PATH"})
    +  my $sep = $^O eq 'os2' ? ';' : ':';
    +  foreach my $dir (reverse split /$sep/, $ENV{"ACLOCAL_PATH"})

Thanks for the report. I added a check for Windows and committed it.
--best, karl.

aclocal: path separator is ; on OS/2 and Windows.

Adapted from and fixes https://bugs.gnu.org/71534.

* bin/aclocal.in (parse_ACLOCAL_PATH): use $^O to recognize OS/2
and Windows for the environment path element separator.
* NEWS: mention this.
