Re: [OMPI devel] 1.4.4rc2 is up
This bug applies to OpenMPI 1.4.x and 1.5.x.
Inline assembly does not work for PGI compilers. configure disables
inline assembly for PGI C, but neglects to do the same for PGI C++.
The code that disables inline assembly for PGI C needs to be copied to
the section that handles inline assembly for C++.
Here's the diff -u from OpenMPI 1.4.3 (same code, same bug):

Re: [OMPI devel] 1.4.4rc2 is up
This bug applies to OpenMPI 1.4.x and 1.5.x.
The libtool.m4 in config and opal/libltdl/m4 do not properly determine
the version of the PGI compiler, which then set the wrong compile/link
options. They interpret V11.4 (version no. begins with a 1), for
example, as being a V1 to V5 compiler. There is a missing period in
the pattern, so that only text like 1.x through 5.x matches.
