According to Kernighan&Ritchie (Appendix A, 6.2 on page 184 in my copy)
'all floating point arithmetic in C is carried out in double
precision'.  Therefore, if manx on the AMIGA really uses one longword
for floating point evaluations it simply isn't real C and benchmarks
with this compiler are pure nonsens if compared with 'correct'
C-Compilers using 64bit double precision.
