What about replacing the IBITS statement with "NOT (0)" or "IAND (-1, -1)", or "IOR (-1, 0)" these would then also fall outside the range and not work either? However, they all work fine with version "GNU Fortran (GCC) 4.2.1 (Ubuntu 4.2.1-5ubuntu4)" and they print "-1". On the other hand I get /usr/bin/ld: warning can't open dynamic library: /libgcc_s.1.dylib referenced from: /usr/local/gfortran/lib/gcc/powerpc-apple-darwin8.10.0/4.3.0/../../../libgfortran.dylib (checking for undefined symbols may be affected) (No such file or directory, errno = 2) when I run it on my mac with version "GNU Fortran (GCC) 4.3.0 20071017 (experimental) [trunk revision 129405]" but perhaps that also as it should be?
