        I have noticed a few inconsistencies with the DJGPP compiler over 
other C compilers I use.
        The first one is that the lines:

        for(int i=0; i<256; i++)
        {       someFunction(i);
        }

        won't compile SOMETIMES (?!?!?!), yet the lines:

        int i;
        for (i=0; i<256; i++)
        {       someFunction(i);
        }

        works everytime...why?

        Also, I sometimes get random compiler "parse" errors when I include 
the following code in a program:

        char *str;
        if ( (str = getenv("DEM_PATH")) == NULL) {
                printf("\"DEM_PATH\" environment variable not set\n");
                exit(1);
        }

        Yet again...WHY?
        I really like the DJGPP compiler (just wish I could make it work under 
MSDEV) and the ease of porting to/fro UNIX/DOS.  Makes college life a helluva 
lot easier...but these compiler problems bother me as far as how "compatible" 
DJGPP really is.  Anyone have any comments?

                                                                PV
