Yes, but fast if not already too late.  Small patches.

| - a new macro: AC_PATHSEP

|   the build system (as found in $ac_pathsep; see below)
|   This is mainly for use in makefiles and shell scripts (in fact, my
|   patched automake 1.4a relies on it to get its TeX-related rules right).

Good idea.

| - AC_PATH_PROG(s) don't return a full path if configure run under DJGPP.
|   This is because we want the produced files to be portable across DOS
|   based systems, and to keep DOS paths out of autoconf variables as much
|   as possible (as the colon used in a drivespec often causes trouble for
|   autoconf, which uses the colon for its own purposes).

Dunno.  Can't you fix the uses of `:'.  That's how we did currently.

| I've also added a _AC_DJGPP macro to the _AC_EXEEXT mechanism, but this

I think the current CVS Autoconf makes this useless.

I don't like ac_test_f, and my understanding was that it is no longer
needed.  Promote upgrading DJGPP.

The problem is that care must be taken, and it's too late now, 2.50
must be _out_.  We will see for 2.51 though.
