f2547368a8 With current pthread implementations, a mutex initialization will
allocate a memory block. sscanf calls __svfscanf which in turn calls
fread, fread triggers mutex initialization but the mutex is not
destroyed in sscanf, this leads to memory leak. To avoid the memory
leak and performance issue, we create a none MT-safe version of fread:
__fread, and instead let __svfscanf call __fread.

94b1a9eeaf - To make it easier to compile *printf() and *scanf() without
floating-point support, remove default definition of FLOATING_POINT
  from the source, and change the compile-time option to
  NO_FLOATING_POINT.
- Remove the HEXFLOAT option.  It saves an insignificant amount of
  space (<0.1% of the size of libc on i386) and complicates vfprintf()
  and checkfmt().

While here, add %a and %A, which are aliases for %e, and

097dea9b47 Implement several of the c99 updates to scanf(3):
- New length modifiers: hh, j, ll, t, z.

Still to do:
 - %C, %S, %lc, %ls (wide character support)
 - %a/%A (exact hex representation of floating-point numbers)

Removed old compatability equivalents:
 - %D for %ld, %O for %lo, %X for %lx, %E and %F for %le & %lf (these
   were buggy anyway, since they should have represented %Le & %Lf).
 - %[unknown uppercase char] for %ld, %[unknown lowercase char] for %d

0c2addad83 Back out national digits support, POSIX explicetely disallows it:
The definition of character class digit requires that only ten characters
-the ones defining digits- can be specified; alternate digits (for
example, Hindi or Kanji) cannot be specified here. However, the encoding
may vary if an implementation supports more than one encoding.

The definition of character class xdigit requires that the characters
included in character class digit are included here also and allows for
different symbols for the hexadecimal digits 10 through 15.

1635c221b7 Remove _THREAD_SAFE and make libc thread-safe by default by
adding (weak definitions to) stubs for some of the pthread
functions.  If the threads library is linked in, the real
pthread functions will pulled in.

Use the following convention for system calls wrapped by the
threads library:
	__sys_foo - actual system call
	_foo - weak definition to __sys_foo
	foo - weak definition to __sys_foo

Change all libc uses of system calls wrapped by the threads
library from foo to _foo.  In order to define the prototypes
for _foo(), we introduce namespace.h and un-namespace.h
(suggested by bde).  All files that need to reference these
system calls, should include namespace.h before any standard
includes, then include un-namespace.h after the standard
includes and before any local includes.  <db.h> is an exception
and shouldn't be included in between namespace.h and
un-namespace.h  namespace.h will define foo to _foo, and
un-namespace.h will undefine foo.

Try to eliminate some of the recursive calls to MT-safe
functions in libc/stdio in preparation for adding a mutex
to FILE.  We have recursive mutexes, but would like to avoid
using them if possible.

Remove uneeded includes of <errno.h> from a few files.

Add $FreeBSD$ to a few files in order to pass commitprep.

This makes us in line with SunOS 4.1.3_U1, Solaris 2.6, OpenBSD 2.3,
HP-UX 10.20, Irix 5.3.  The previous behavior was in line with Ultrix 4.4.

4037ac32c7 Fixed long double formats. They were mostly not implemented except
on systems where long doubles are just doubles.  FreeBSD hasn't
been such a system since it started using gcc-2.5 many years ago.
The fix is of low quality.  It loses precision.

scanf() of long doubles doesn't seem to be used much, but gdb-4.16
uses %Lg format in its expression parser if it thinks that the
system supports printf'ing of long doubles.  The symptom was that
floating point literals were usually interpreted to be 0.0.

6c38eceeb9 Fixed handling of input failure by the scanf family.
- 0 was returned instead of EOF when an input failure occured while
  skipping white-space after 0 assignments.  This fixes PR2606.  The
  diagnosis in PR2606 is wrong.
- EOF was returned instead of 0 when an input failure occurred after
  zero assignments and nonzero suppressed assignments.
- EOF was spelled -1.

This should be in 2.2.

fac2ce3b12 Suggested by: Bruce Evans, Jeffrey Hsu, Gary Palmer
Added $Id$'s to files that were lacking them (gpalmer), made some
cosmetic changes to conform to style guidelines (bde) and checked
against NetBSD and Lite2 to remove unnecessary divergences (hsu, bde)

One last code cleanup:-

Removed spurious casts in fseek.c and stdio.c.
Added missing function argument in fwalk.c.
Added missing header include in flags.c and rget.c.
Put in casts where int's were being passed as size_t's.
Put in missing prototypes for static functions.
Changed second args of __sflags() inflags.c and writehook() in vasprintf.c
from char * to const char * to conform to prototypes.

This directory now compiles with no warnings with -Wall under
gcc-2.6.3 and with considerably less warnings than before with the
ultra-pedantic script I used for testing. (Most of the remaining ones
are due to const poisoning).
