Hi Tony, hallo Marc

I've attached a patch for the interpreter that should fix this issue for
gcc-compiled interpreter on all platforms. It works for me on mips-irix and
i386-linux interpreters. 

* It removes the *_MODULO_BROKEN and *_DIVISION_BROKEN test from the configure
script, since it's pointless to test for undefined behaviour. 
* It changes long_rem and int_rem definitions to explicitely test for -1 as the
dividend, and return 0 in that case, like the spec demands. 
* It also fixes int_div and long_div to check for MIN_VALUE / -1 and return
MIN_VALUE in that case, according to the spec. 
* It adds JINT_MIN and JLONG_MIN to jtypes.h.in.

could you give it a try on m68k and powerpc?
