I think this is correct.

Per says system has no specific argument for this purpose.  In barbaric
desperation I tried:
CFLAGS='-hfloat0 -Dint=long' \
However (as one example) /usr/include/stdio.h
contains line
        short    int    _smode; /* stream mode */
which made this fail.  

Per suggested using
    typedef long int;
Can you suggest a way of specifying this typedef?
It is a pity that there is no argument like gcc "-include file" to read
a specified include file before processing the regular input file.

Thanks,
Harvey
