+This subsystem ensures that we can always use a certain core set of 
+functions and types, that are either provided by the OS or by replacement 
+functions / definitions in this subsystem. The aim is to try to stick 
+to POSIX functions in here as much as possible. Convenience functions 
+that are available on no platform at all belong in other subsystems
+(such as LIBUTIL).
+
+The following functions are guaranteed:
+
+ftruncate
+strlcpy
+strlcat
+mktime
+rename
+initgroups
+memmove
+strdup
+setlinebuf
+vsyslog
+timegm

+/**************************************************************
+ * Original:
+ * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
+ * A bombproof version of doprnt (dopr) included.
+ * Sigh.  This sort of thing is always nasty do deal with.  Note that
+ * the version here does not include floating point...
+ *
+ * snprintf() is used instead of sprintf() as it does limit checks
+ * for string length.  This covers a nasty loophole.
+ *
+ * The other functions are there to prevent NULL pointers from
+ * causing nast effects.
+ *
+ * More Recently:
+ *  Brandon Long <blong@fiction.net> 9/15/96 for mutt 0.43
+ *  This was ugly.  It is still ugly.  I opted out of floating point
+ *  numbers, but the formatter understands just about everything
+ *  from the normal C string format, at least as far as I can tell from
+ *  the Solaris 2.5 printf(3S) man page.
+ *
+ *  Brandon Long <blong@fiction.net> 10/22/97 for mutt 0.87.1
+ *    Ok, added some minimal floating point support, which means this
+ *    probably requires libm on most operating systems.  Don't yet
+ *    support the exponent (e,E) and sigfig (g,G).  Also, fmtint()
+ *    was pretty badly broken, it just wasn't being exercised in ways
+ *    which showed it, so that's been fixed.  Also, formatted the code
+ *    to mutt conventions, and removed dead code left over from the
+ *    original.  Also, there is now a builtin-test, just compile with:
+ *           gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
+ *    and run snprintf for results.
+ *
+ *  Thomas Roessler <roessler@guug.de> 01/27/98 for mutt 0.89i
+ *    The PGP code was using unsigned hexadecimal formats.
+ *    Unfortunately, unsigned formats simply didn't work.
+ *
+ *  Michael Elkins <me@cs.hmc.edu> 03/05/98 for mutt 0.90.8
+ *    The original code assumed that both snprintf() and vsnprintf() were
+ *    missing.  Some systems only have snprintf() but not vsnprintf(), so
+ *    the code is now broken down under HAVE_SNPRINTF and HAVE_VSNPRINTF.
+ *
+ *  Andrew Tridgell (tridge@samba.org) Oct 1998
+ *    fixed handling of %.0f
+ *    added test for HAVE_LONG_DOUBLE
+ *
+ * tridge@samba.org, idra@samba.org, April 2001
+ *    got rid of fcvt code (twas buggy and made testing harder)
+ *    added C99 semantics
+ *
+ * date: 2002/12/19 19:56:31;  author: herb;  state: Exp;  lines: +2 -0
+ * actually print args for %g and %e
+ *
+ * date: 2002/06/03 13:37:52;  author: jmcd;  state: Exp;  lines: +8 -0
+ * Since includes.h isn't included here, VA_COPY has to be defined here.  I don't
+ * see any include file that is guaranteed to be here, so I'm defining it
+ * locally.  Fixes AIX and Solaris builds.
+ *
+ * date: 2002/06/03 03:07:24;  author: tridge;  state: Exp;  lines: +5 -13
+ * put the ifdef for HAVE_VA_COPY in one place rather than in lots of
+ * functions
+ *
+ * date: 2002/05/17 14:51:22;  author: jmcd;  state: Exp;  lines: +21 -4
+ * Fix usage of va_list passed as an arg.  Use __va_copy before using it
+ * when it exists.
+ *
+ * date: 2002/04/16 22:38:04;  author: idra;  state: Exp;  lines: +20 -14
+ * Fix incorrect zpadlen handling in fmtfp.
+ * Thanks to Ollie Oldham <ollie.oldham@metro-optix.com> for spotting it.
+ * few mods to make it easier to compile the tests.
+ * addedd the "Ollie" test to the floating point ones.
+ *
+ * Martin Pool (mbp@samba.org) April 2003
+ *    Remove NO_CONFIG_H so that the test case can be built within a source
+ *    tree with less trouble.
+ *    Remove unnecessary SAFE_FREE() definition.
+ *
+ * Martin Pool (mbp@samba.org) May 2003
+ *    Put in a prototype for dummy_snprintf() to quiet compiler warnings.
+ *
+ *    Move #endif to make sure VA_COPY, LDOUBLE, etc are defined even
+ *    if the C library has some snprintf functions already.
+ *
+ * Darren Tucker (dtucker@zip.com.au) 2005
+ *    Fix bug allowing read overruns of the source string with "%.*s"
+ *    Usually harmless unless the read runs outside the process' allocation
+ *    (eg if your malloc does guard pages) in which case it will segfault.
+ *    From OpenSSH.  Also added test for same.
+ *
+ * Simo Sorce (idra@samba.org) Jan 2006
+ *
+ *    Add support for position independent parameters
+ *    fix fmtstr now it conforms to sprintf wrt min.max
