Image support on MS OS

Image support on MS OS

[Dhruva Krishnamurthy]

Hello,
 I am using GNU Emacs from CVS Head on W2K built using MinGW and MSVC.
The image support (viewing of images) works in MinGW and not in MSVC
build. But, I can see color tool bar images in both the builds. I am
using MinGW image libraries (could be a cause for error, but I
remember this was working).
 When viewing images (JPEG) in MSVC build, I get the following error:
JPEG parameter struct mismatch: library thinks size is 432, caller expects 464

with regards,
dhruva

We used to get crashes loading JPEGs when using an optimized MSVC
build of Emacs. I can't see that error message in Emacs, so maybe the
author of the jpeg library has added detection of the problem. As I
suspected, the alignment of struct members is probably affected by an
optimization option, though I wonder why this is not a major problem
for users of MSVC when using external libraries.
