[mpich-discuss] issue compiling mpich

[chan at mcs.anl.gov]

Unset your CFLAGS and CPPFLAGS in your configure command
and try again.  Largefile support is enabled by default if
it is available.  CPPFLAGS stands for "C PreProcessor FLAGS"
not "C++ FLAGS"  Setting it incorrectly is the likely reason
of your configure failure.
