Ralph, Please note that I saw no problems with pgi-9,10,11,13 or 14. Only pgi-12 was complaining. So, I am fairly confident that pgi-12.10 (the final in the 12.x series) is broken, but that PGI is "OK" in general with respect to C99.
As 2.x nears readiness, it seems possible that the README will need to enumerate C compilers with broken C99 support. -Paul On Fri, Jul 17, 2015 at 2:32 PM, Ralph Castain <r...@open-mpi.org> wrote: > I went ahead and removed those, but this raises a rather major red flag > for us.
