Hm, I miss a point here: I don't quite understand how it relates with
AC_PATH_PROG since this macro considers the absolute/relative thing
only when checking the envvar that should point to the tool (e.g.,
PERL=/usr/bin/perl).
I can imagine there is a problem with IFS=: to split the PATH, but I
don't quite understand how your patch improves the situation.
