[GRASS5] What's holding 5.3.0 release?

It should be working now, please test.


You are likely to see some "depreciated" messages, but there's not much
we can do about that without breaking compatibility with gcc 2.95s.

... having said that ...

I think the best way to fix it is as Laura suggested, to use the
shortened include names if gcc version>=3.2, and in all other cases (and
compilers) use full <name.h>. Someone with gcc 3.0 might tell us if it
includes <ostream> so we can get the minor version correct?


#if __GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ >= 1)
#include <ostream>
#else
#include <ostream.h>
#endif

etc

This should make it compile cleanly for both gcc 2.95 and 3.x and fix
the error Paul saw using IRIX's CC:
  http://article.gmane.org/gmane.comp.gis.grass.devel/2896



e.g. a test for gcc version >=3.1,

#include <stdio.h>

int main(void) {

#if __GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ >= 1)
    printf("new gcc version %d.%d\n", __GNUC__, __GNUC_MINOR__);
#else
    printf("not a modern gcc\n");
#endif

    return 0;
}
