I found another way: leverage the llrint() implementation in MinGW.
a) We need first to download the mingw-runtime Cygwin package.
b) Then we create a small library:
ar x /usr/lib/mingw/libmingwex.a llrint.o
ar cq /usr/local/lib/libllrint.a llrint.o
c) And

This is a very, very bad idea. MinGW uses a completely different and

You're getting the number wrong, it should be somewhere in the 137000 range.
Take a look at the message for the Original-X-From: and Return-path: headers.

A builtin in gcc has a specific meaning, and it does not mean that the
compiler provides a full implementation of that function. What it means

I never claimed that we do not *have* OS-specific workarounds, I said

That's a vey fine distinction and was not at all clear from the

According to Diego Biurrun on 9/29/2007 1:14 PM:
What's wrong with adding llrint to your code (perhaps with a #define,
i.e.,
#define llrint my_llrint
typeof(llrint) my_llrint(...) { ... }
)?
It is ugly and it is a workaround for a problem
