Hooray!

At Long Last, I have succeeded in making mapscript with python compile, 
for mapserver-4.0b. I finally found the error, which is in 'pymodule.i'. 
Here it is...

The function  _raise_ms_exception() begins with the following code:

static void _raise_ms_exception(void) {
        char errbuf[256];
        char errmsg[2048]; // room for up to 8 * 256 byte messages
        int errcode;

        strcpy(errmsg, "");
        errorObj *ms_error = msGetErrorObj();
        errcode = ms_error->code;

The highlighted line is valid C++, but is not valid C (at least it 
wasn't valid in my olden days as a C programmer, or according to 
gcc-2.95). I have repaired this by separating the declaration and 
assignment:

static void _raise_ms_exception(void) {
        char errbuf[256];
        char errmsg[2048]; // room for up to 8 * 256 byte messages
        int errcode;
        errorObj *ms_error;

        strcpy(errmsg, "");
        ms_error = msGetErrorObj();
        errcode = ms_error->code;

and now it all compiles successfully on RedHat 7.3 and Debian (woody). I 
also had to mangle setup.py to make it work on my system. I'll send my 
changes to Sean Gillies, who has helped me out with this mess.

THANKS for the help, folks!
Vic
