[mpich-discuss] installing mpich2 into mac os

[chan at mcs.anl.gov]

Is the reason of using -no-multibyte-chars is to avoid a null locale setting ?
If so, you may want to set LANG=C or/and LC_ALL=en_US in your shell setup file
(i.e. .cshrc/.bashrc) and drop all -no-multibyte-chars to all compilers and
preprocessor.

PS. I have no access to mac with intel compiler, so can't confirm this.
