Use libc from agbcc instead of standalone newlib\nYou must have AGBCC commit 80d029caec189587f8b9294b6c8a5a489b8f5f88 in order to compile pmd_red.gbalibc

-FUNCTION
-<<fread>>---read array elements from a file
-
-INDEX
- fread
-
-ANSI_SYNOPSIS
- #include <stdio.h>
- size_t fread(void *<[buf]>, size_t <[size]>, size_t <[count]>,
- FILE *<[fp]>);
-
-TRAD_SYNOPSIS
- #include <stdio.h>
- size_t fread(<[buf]>, <[size]>, <[count]>, <[fp]>)
- char *<[buf]>;
- size_t <[size]>;
- size_t <[count]>;
- FILE *<[fp]>;
-
-DESCRIPTION
-<<fread>> attempts to copy, from the file or stream identified by
-<[fp]>, <[count]> elements (each of size <[size]>) into memory,
-starting at <[buf]>. <<fread>> may copy fewer elements than
-<[count]> if an error, or end of file, intervenes.
-
-<<fread>> also advances the file position indicator (if any) for
-<[fp]> by the number of @emph{characters} actually read.
-
-RETURNS
-The result of <<fread>> is the number of elements it succeeded in
-reading.
-
-PORTABILITY
-ANSI C requires <<fread>>.
-
-Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
-<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
