Clean up warnings, switch library code to use Standard C/POSIX wrapper
macros, remove internal calls to API routines, update checkapi and checkposix
scripts.
Tested on:
Mac OSX/64 10.8.3 (amazon) w/C++ & FORTRAN
Big-Endian Linux/64 (ostrich)
The daily tests run copies of some of the scripts in this directory from another repository, notably snapshot and runtest. The copies in this directory should work, but are not used in daily tests, though they should be tested occasionally.
