No, do not do that. It's wrong and doesn't help (thats at least my view).
This 'No such file or directory' error could happen with the old version,
which was 'error = error < 1 ? errno : error;', because errno could be
nonzero, while error was zero. this is due to getpwuid_r trying to open
different files in order, where the first calls might fail.

just look in configure.in ;-)

The last commit should actually work now. (I've heard that times and times
before ;-)

Bye,
Sebastian
