[PATCH 0/5] fix up 'jk/pack-bitmap' branch

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Hi Jeff,

These patches fix various errors/warnings on the cygwin, MinGW and
msvc builds, provoked by the jk/pack-bitmap branch.

Note that this does not fix all problems on the msvc build; I have
a solution, but I don't like it. :-D  So, I'm going to try a different
fix. I had hoped to have done this by now, but ... (hopefully, sometime
this weekend).

Note that I have only tested the cygwin and MinGW builds by running
the t5310-pack-bitmaps.sh test, and only on a little-endian machine.
(Torsten has tested the first patch on a big-endian)

Note also, that these patches are build on top of the 'pu' branch
as of yesterday (pu @ 2b65d9ebc).

So, could you please squash these patches into the relevant commits
on your branch.

Thanks!

ATB,
Ramsay Jones
