Details:
If a configure script uses AC_CHECK_PROG to find a program, then the person
running configure can use "./configure PROGRAM=renamed" to direct configure to
use a different name for the program. However, if it uses AC_PATH_PROG, then
the person running configure must supply an absolute path to PROGRAM,
otherwise the setting is silently ignored. This is confusing. If given a
relative path, it should convert it to an absolute one; if given a basename,
it should walk $PATH for that name instead.
