#9 need this to compile with gcc 4.1

[Tom Horsley]

As noted elsewhere, I have to force the -m32 option
to build on a 64 bit system, but in addition to that,
I got errors about conflicting C and C++ signatures
for some global variables (this was on a Fedora Core 6
system). The attached patch fixes the problem and seems
to build a working tesseract.

I doubt this is the "right" patch, but it does allow
it to build.

Here is the patch needed to compile it for 64 bits architectures (assume C99 compatible compiler):

Grumpf...

Be careful, some \newlines have been inserted in the patch and might be misinterpreted. Typically:

The (chunk + chuncksize) is in fact subtracted from the previous line (and not suppressed from the code).
Sorry for that I didn't find the way to upload this patch as a file.
