BUG: Avoid SGI preprocessor bug for Fortran Id
The SGI preprocessor /usr/lib/cpp produces bad output on this code:
#if 1
A
#elif 1
B
#else
C
#endif
Both 'A' and 'C' appear in the output! We work around the problem by
using '#elif 1' instead of '#else'.
This fixes detection of the SGI Fortran compiler id in -o32 mode.
