 * fputc_ - write a character to a logical unit bypassing f77
 *          formatted I/O. fputc is called from f77 and f90 programs
 *          on mips only.  fgetc only applies to unit 6.  The clen
 *          arg is ignored since only a single character is written.
 *

 *      INTEGER fputc, unit, ierror
 *      ierror = fputc (unit, char)

 * where:
 *
 *      char    = write char to the logical unit
 *      ierror  = 0 if successful
 *              = a system error code otherwise.
 *
 * Call fputc_ from MIPS F77 or from MIPS F90 without a
