ISO C99 and later do not support implicit int

Hi,

I am trying to build mpiP using "icx" on intel CPUs, but met the following issue. how to fix it?

pc_lookup.c:115:41: error: parameter 'data' was not declared, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int]

make: *** [Rules.mak:6: pc_lookup.o] Error 1

Reproduce the failure with icx and inspect pc_lookup.c around lines 115-119, then trace the PTR references near lines 438 and 479-480. The change is complete when mpiP builds successfully with the reported compiler errors resolved.
