GCC now complains if `main` has no explicitly declared return type.
Because `bfr`s `configure` script uses a very minimal C application
to check whether GCC works _at all_ (literally: `main(){return(0);}`),
this caused configure failures.
Another issue with the `configure` script is that it logs the compiler
errors for its checks to `configure.log` (and not to stdout or stderr),
which means that the root cause wasn't logged during the failed nix
build.
I added a patch that rewires the compiler error file descriptor so
that it will simply log to stderr and another patch that fixes the
missing return type in the C example.
Unfortunately, it looks like the server isn't serving the source
files anymore (and finding an official upstream repo which I could
send a PR to seems... non-trivial).
