[mpich-discuss] ROMIO compiler warnings

[Jeff Squyres]

Here's a typical set of build flags:

-g -Wall -Wundef -Wno-long-long -Wsign-compare -Wmissing-prototypes -Wstrict-prototypes -Wcomment -pedantic -Werror-implicit-function-declaration -finline-functions -fno-strict-aliasing -pthread -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -DHAVE_ROMIOCONF_H 

Does this help?
