[pooma-dev] RFA: SGI CC Header Files

[Julian C. Cummings]

I have all of the replacement new-style C header files
for the SGI compiler set up and ready to be checked in.
I tested them by compiling src/Utilities/tests/delete_test1.cpp
under SGI CC.  In order to do this, I had to add the
following two includes to delete_test1.cpp:

#include <cstdlib>  // needed for std::rand()
#include <cstring>  // needed for std::memmove()

So I would propose that you augment whatever patch you
come up with for delete_test1.cpp to also add these
two include statements.  

If I don't hear any objections, I will check in the 
replacement header files for SGI CC sometime over the
weekend.

Thanks, Julian C.

It's fine with me.
