Patch from Ian Lance Taylor <ian@airs.com>:

    The reentrant versions of the malloc functions in
        c/src/lib/libc/malloc.c
    do not match the definitions in newlib.  These will be used if you use
    newlib routines such as fdopen.  I believe this patch to malloc.c is
    needed to provide the correct versions.
