program to load a bitmap from command line, display on screen

I was hunting around for small windows programs to display bitmaps via GDI so
that I could test the bitmap display code in Wine (to follow an afterthought I
had relating to bug 14868). Since I wasn't able to find anything, I decided to
write my own (attached), then run it through Jason Summers' bitmap test suite
(http://entropymine.com/jason/bmpsuite/reference/reference.html). One of these
bitmaps failed the test (g08offs.bmp), appearing different to the reference
image. According to the reference page, the "... bfOffBits in [the] header not
set to the usual value. There are 100 extra unused bytes between palette and
bits."

The program has been compiled with mingw32 (Version 4.2.1.dfsg-1) on a Debian
system (see Makefile for full parameters etc.).

Running Wine off a git branch pulled ~1.5 days ago, with patch from bug 14868.
