Subject: [OMPI devel] oshmem and CFLAGS removal
From: Rolf vandeVaart (rvandevaart_at_[hidden])

I noticed that there were some CFLAGS that were no longer set when enabling with --enable-picky for gcc. Specifically, -Wundef and -pedantic were no longer set.
This is not a problem for Open MPI 1.7.

I believe this is happening because of some code in the config/oshmem_configure_options.m4 file that is supposed to be oshmem specific, but seems to be bleeding into everything that gets compiled.


# Strip off problematic arguments
oshmem_CFLAGS="`echo $oshmem_CFLAGS | sed 's/-pedantic//g'`"
oshmem_CFLAGS="`echo $oshmem_CFLAGS | sed 's/-Wundef//g'`"
oshmem_CFLAGS="`echo $oshmem_CFLAGS | sed 's/-Wno-long-double//g'`"

Does anyone know an easy fix for this? This is why I think some warnings appeared in Open MPI 1.7 that we did not see for the same change in the trunk.
