If the buffer mode is set to "no buffering" then fread() will always bypass the buffer and call read() instead.
If there is enough data waiting to be read from the buffer, fread() will now copy it directly, refilling the buffer as needed.
If the read buffer happens to be empty, buffering is enabled for the stream, and the number of bytes to read is at least as large as the buffer size, then fread() will directly call read(), which should improve performance significantly.
- Replaced ISO Latin 1 code #160 with a plain blank space (ASCII code #32) where necessary

of records or the size of each record is zero, both now call clearerr() to
avoid giving the caller the wrong impression that an EOF or error occured.

and ftrylockfile().
- Modified the internal FILE structure to allow for thread locking.
Note that this again requires that the library is rebuilt!
- Added or modified macros for getc_unlocked(), getchar_unlocked(),
putc_unlocked() and putchar_unlocked().
- Added rand_r().
- Added flockfile()/funlockfile() wrappers around all stdio
functions.

code which initialized them.
- Reading/changing the errno variable is no longer done directly, but
involves accessor functions.
- References to the HUGE_VAL quantity now involve an accessor function, too.
- Changed the manner in which the __huge_val constant is initialized by
the __math_init() function.
