Subject: Re: [OMPI devel] "make check" (libtool) failure on Linux/ppc w/ XLC (1.5rc5 and 1.4.3rc1)
From: Ralf Wildenhues (Ralf.Wildenhues_at_[hidden])

Hello Paul,

this bug has been addressed in upstream Libtool commit

It is not wholly fixed yet, but for all cases interesting to OpenMPI.
(A libtoolized package using only Fortran but no C compiler may still
have issues.)
