For what it's worth, I count 13 instances of 'int main (void) { ... }' in Gnulib 
code, and 136 instances of 'int main () { ... }'. As I recall, the latter is for 
C++ compatibility, which I guess is not an issue with MPFR.

It's not a big deal either way, but if it helps MPFR out I suppose it's a win. I 
installed the attached two patches. The first one fixes the problem you 
mentioned, along with a similar issue in the 'inline' detection. The second one 
fixes a related problem with 'int main (int argc)'.
