Aside from the fact that this produces a confusing name for a 64-bit
Per the comment there: "INT32 must hold *at least* signed 32-bit values"
it conflicts with /usr/include/w32api/basetsd.h, which has
typedef signed int INT32
This causes a problem for the build of emacs-w32.
Fortunately, the code doesn't seem to care about consistency in this
type. Even on Linux, when itself is compiled for x86-64 this will be a
64-bit signed type, but when the header is used in conjunction with X11
headers (which have a typedef int INT32;), jmorecfg.h uses that and
skips its own typedef.
So it would seem we could do the same with w32api:
=== BEGIN ===
@@ -161,4 +161,6 @@
#ifndef XMD_H /* X11/xmd.h correctly defines INT32 */
+#ifndef _BASETSD_H_ /* w32api defines this in basetsd.h */
typedef long INT32;
=== END ===
It does mean that Win32API (or X11, for that matter) headers must be
#include'd before <jpeglib.h>. Before I spin a new release, could you
test if this works with emacs?
Yes, it works. Thanks.
