  I am almost done porting https://savannah.gnu.org/projects/lightning
to cygwin and windows64 abi. But I found a problem with the ffs function.

  The test case is simple:

$ cat x.c
extern int ffs(int);
int main(void) {
long l = 0x80000000;
int i = ffs((int)l);
return 0;

$ gcc -O0 -g3 x.c

$ ./a.exe
Segmentation fault (...)
