(SPARC) Prepare for linking with runtime libraries compiled with earlier versions of f77.
f95 -xlang=f77 implies linking with the f77compat library, and is a shorthand way for linking Fortran 95 object files with older Fortran 77 object files. Compiling with this flag insures the proper runtime environment.
Use f95 -xlang=f77 when linking f95 and f77 compiled objects together into a single executable.
Note the following when compiling with -xlang:
Do not compile with both -xnolib and -xlang.
When mixing Fortran object files with C++, link using the C++ compiler and specify -xlang=f95 on the CC command line.
When mixing C++ objects with Fortran object files compiled with any of the parallelization options, the linking CC command line must also specify -mt.
