CVS Emacs problem with TRUE in src/image.c

When building GNU Emacs from CVS on Debian GNU/Linux 3.0r2 I ran into
the following problem:

   gcc -c -D_BSD_SOURCE   -Demacs -DHAVE_CONFIG_H   -I. 
-I/home/eggert/src/gnu/emacs-error/src -D_BSD_SOURCE -I/usr/X11R6/include -g 
-O2 image.c
   image.c: In function `Finit_image_library':
   image.c:7955: error: `TRUE' undeclared (first use in this function)
   image.c:7955: error: (Each undeclared identifier is reported only once
   image.c:7955: error: for each function it appears in.)
   image.c: In function `init_image':
   image.c:8117: error: `TRUE' undeclared (first use in this function)
   make[1]: *** [image.o] Error 1
   make[1]: Leaving directory `/home/eggert/src/gnu/emacs-error/src'
   make: *** [bootstrap-build] Error 2


Here is a trivial patch to src/image.c to work around the problem:

2004-12-07  Paul Eggert  <address@hidden>

        * image.c (our_fill_input_buffer, jpeg_load, CHECK_LIB_AVAILABLE,
        init_image): Use 1 rather than TRUE, since TRUE isn't defined on
        Debian GNU/Linux 3.0r2.
