[MOAB-dev] Issues with default gfortran compiler on fusion

[Xiabing Xu]

I have a problem working with a library requiring a predefined macro __SIZEOF_SIZE_T__ on fusion.

By running the following command, I can get a list of predefined macros.
touch foo.F; gfortran -E -dM foo.F

However, the __SIZEOF_SIZE_T__ is missing. 

According to the gcc manual, the __SIZEOF_SIZE_T__ should be defined in common cases.
http://gcc.gnu.org/onlinedocs/cpp/Common-Predefined-Macros.html

Is there any specific reason that this macro is disabled? Or is it because gfortran compiler used on fusion is too old?

Thanks,

Xiabing
