JPEG - GNU Emacs 21.3.50.1

JPEG - GNU Emacs 21.3.50.1

[Dhruva Krishnamurthy]

Hello,
 I tried building Emacs with JPEG support using the MinGW & JPEG 6.0.
INT32 is getting redefined in the MinGW tools distribution's "basetsd.h" 
file and JPEG's "jmorecfg.h" file. I had to alter the "jmorecfg.h" and
prevent the redefinition by putting it in a "#ifdef emacs" block. Is
there a way to avoid redefinition of typedefs in 'C'?
I could then build the Emacs (emacs-version):
GNU Emacs 21.3.50.1 (i386-mingw-nt5.0.2195) of 2003-02-03 on WOLFDEI

PS: Can I use GTK build on Windows? I have GTK for Windows.

with regards,
dhruva

Why?

I mean, it is causing you trouble the redefinition? With the MSVC
compiler, the warning says: "warning C4142: benign redefinition of type",
because it is redefining a type with another one of the same size.

You could do preprocessor tricks (renaming things before including the
relevant header, for example).

Sorry, no.  The event code uses functions that exist only in the X11 part
of GTK.

The sources at gnuwin32.sourceforge.net prevent the redefinition with
#ifndef _WIN32_, so this seems to be a general problem with mingw32
and the jpeg library. Probably this should be reported to the
maintainers of jpeg-6b.

AFAIK, no. The GTK build still uses X specific features.
