The library libxlf90_r.a is a superset of libxlf90_t.a, which is a partial thread-support run-time library. The file xlf.cfg has been set up to link to libxlf90_r.a automatically when you use the xlf90_r, xlf90_r7, xlf95_r, xlf95_r7, xlf_r, and xlf_r7 commands. Setting Up and Customizing XL Fortran 23
