Subject: [PATCH] Turned on the setting of FTN_TRAILING_UNDERSCORE,
 LAPACK_FTN_STRING_LEN_AT_END, LAPACK_NAME_LOWERCASE, and
 LAPACK_FTN_TRAILING_UNDERSCORE in the config.h.in file. Previously they
 defaulted to being "defined". Now they are user-configurable, with the
 default being that they are "defined".
