[mpich-discuss] configuration issues: complex.h and CROSS_F77_SIZEOF_INTEGER

[Lou Picciano]

Attempting to configure mpich-3.2b1 for the SolarisStudio12.4 suite... 

Issues around complex.h (Yes, I'll have to look for prerequisites) 

and the message about FORTRAN integer length - which seems to have been dealt with a couple of years ago, and only in the ifort context? 

CROSS_F77_SIZEOF_INTEGER seems to be ignored; I've tried all of 1,2,4,8... 

Many thanks!
