[mpich-discuss] ROMIO compiler warnings

[Jeff Squyres]

I notice that gcc 4.1 and 4.5 issue a bunch of warnings with the ROMIO from MPICH2 v1.3.1.  Are these warnings that you care about, perchance? 

The output below is from compiling on a RHEL 5.5 machine using the gcc 4.5.0 compilers (snipped output below to show just the warnings):
