I agree it is a bit hairy. Perhaps not ideal; even though this is a rewrite it
has suffered some legacy "lava flow" itself, being in development for so long.
The idea here is. that NOFIXPATH (or not) as $4 is passed to
UTIL_FIXUP_EXECUTABLE. If it is set, then UTIL_FIXUP_EXECUTABLE will never
prepend FIXPATH. Otherwise, UTIL_FIXUP_EXECUTABLE will do the check you are
requesting, and see if we are on Windows and it is a non-unix-aware executable,
and if so, prepend FIXPATH.
So when we come back to UTIL_LOOKUP_PROGS, if we don't have NOFIXPATH, and we
are on Windows (FIXPATH is non-empty) and the path we got from
UTIL_FIXUP_EXECUTABLE starts with FIXPATH, then we remove all instances of
FIXPATH, and prepend a single FIXPATH instance.
While seems like unneccessary work. I ran into situations where I got a double
FIXPATH prefix. It might have been the result of some other bug that is fixed
by now, but costs very little to keep this as a safeguard. It should get a
comment, though, describing what it does.
