I looked into this a little. It looks like the PPL checks don't work

Were you using a --prefix? The PPL checks (by design I think) only look for
PPL in your prefix.
Sorry DaveK, are you talking of only the MELT branch or of the current
gcc trunk (future 4.5)? In the latter (trunk) case, what is the
rationale for checking only in the prefix?
I have to clean up a bit my MELT's gcc/configure.ac, but I cannot
understand why apparently the trunk's gcc/configure.ac does not set any
HAVE_ppl flag.
Why is there no
if test "x${PPPLLIBS}" != "x" ; then
AC_DEFINE(HAVE_ppl, 1, [Define if PPL is in use.])
fi
near line 4110 of the trunk's gcc/configure.ac ?
IMHO, such a test and such a generated #define makes a lot of sense (at
least inside plugins).
Regards.
