Disabling them breaks build on archs using GCC. The problem is at line 156 of
bits/basic_ios.h:
if (this->exceptions() & __state)
__throw_exception_again;
With exceptions disabled __throw_exception_again is defined as
#define __throw_exception_again
at line 45 of exception_defines.h and the code results in an empty loop body,
which fails because of -Werror.

This reduces the lines of code by roughly 50% (not counting the COPYRIGHT
header) and makes it more readable by using standard algorithms.

Instead of digging through the utmp database by hand, use proper API
calls to do so. Instead of parsing entries with a non-empty ut_user, we
now look at LOGIN_PROCESS entries.
