From fa8fda77b3ddc554238a9e677fa79d0629217458 Mon Sep 17 00:00:00 2001

Subject: [PATCH] - Add calls for new macros:   - LAM_SETUP_F77 (moved
 pre-existing F77 code to this macro)   - LAM_SETUP_F90   - LAM_C_WEAK_SYMBOLS
 - Do handling for figuring out whether we need to compile in  
 src/mpi/*/profile or not

This commit was SVN r110.
