#idef 'ing out the call to _tcc_fpinit works.
I tried (blindly) substituting __fixsfdi for __tcc_cvt_ftol in an #ifdef in
tcctok.h ;
the result of the following program produces ridiculous results:
int y = (int)(25.0 * ((double)rand() / (double)RAND_MAX));
printf("y = %d\n",y);
On my test machine, this gives 1610612736, well above 25.
I'd like to push a patch for this issue, but I am still
unsure as to how to fix the problem.
Thanks,
Steve
