As you can see, g++ 4.7.2 reports the missing semicolon error in c.c, not in foo.h

This is a copy of a small C program that prints the largest(?) known Mersenne prime from http://bellard.org/mersenne.html. The file size is slightly larger than the 438 bytes mentioned on the web page, probably because of line breaks.

The original version generates a very large object file because of the large initialized static array.

In response to this question:

This works correctly for me on Ubuntu, and produces the same output each time I run it.

Compile with:

gcc c.c -lssl -lcrypto -o c

Run with:
