Subject: 23.2.91; Pretest Windows binary doesn't support PNG images

From: Eli Zaretskii <[email-masked]>

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your report will be posted to the [email-masked] mailing list
and the gnu.emacs.bug news group, and at http://debbugs.gnu.org.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

  emacs -Q
  (image-type-available-p 'png) => t
  C-x C-f some-file.png RET => no image displayed, only an empty box.

Does anyone else using the precompiled Windows binaries of v23.2.91
(from alpha.gnu.org) see this problem?

A binary I compiled myself from the stock v23.2.91 sources shows PNG
images just fine, with the same image libraries.

Sean, did you build the binaries differently from the previous pretest
(23.2.90)?  It does show PNG images on the same machine with the same
image libraries.

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
d:/usr/emacs/etc/DEBUG.
