Version 5.1.1

core library.
* Fix SourceForge bug #59 DGifOpen can segfault if DGifGetScreenDesc fails.
* SourceForge patch #20: In gifalloc, fix usage of realloc() in case of failure.
* Fix SourceForge bug #61 Leak in gifsponge.
Build Fixes
----------
* glibtoolize port fix for OS X.
=============
Changes to the API require a library major-version bump.
Code Fixes
----------
* A small change to the API: DGifClose() and EGifClose() now take a
pointer-to-int second argument (like the corresponding openers)
where a diagnostic code will be deposited when they return
GIF_ERROR. This replaces the old behavior in which the GifFile
structure was left unfreed so the Error member in it could be filled
and remain available. The change was was required because it's
not always possible to free the struct afterwards. Case in point is
a C# wrapper for giflib (or any language/environment where you can't
just free objects allocated in a foreign shared library.)
* Minor fix for SF bug 56; BitsPerPixel may be left as uninitialized
value when reading (truncated) gif.
* Applied SF patch 17: Use a fallback on Windows where mkstemp is not
available.
* Applied SF patch 15: Code hardening, preventing spurious
defective-image messages.
Retirements
-----------
* Removed gif2raw from utils. Its blithe assumption that the EGA16
palette is a reliable default is now about 20 years obsolete. Format
conversion is better done with convert(1) from the ImageMagick suite,
anyway.
a) refer 'perl' in their Makefile, or
b) have a directory name of p5-*, or
c) have any dependency on any p5-* package
Like last time, where this caused no complaints.
