  Interface for perl to IO functions.
  There is a hierarchy of Configure determined #define controls:
   USE_STDIO   - No longer available via Configure.  Formerly forced
                 PerlIO_xxx() to be #define-d onto stdio functions.
                 Now generates compile-time error.

   USE_PERLIO  - The primary Configure variable that enables PerlIO.
                 PerlIO_xxx() are real functions
                 defined in perlio.c which implement extra functionality
                 required for utf8 support.
