Doh!  Silly.  As a lame excuse I'll mention that the original fix was for situations where errno was not 0 before invoking the macro, not where it was set to 0 inside the macro.  However it should have been obvious that the latter was necessary as well.

Fix applied.

The macro ENULLLOOP in make.h does not work as expected to be fixed in bug #2846.
If "_c" returns zero with errno=EINTR when called first, the inner while-loop repeats calling "_c", but without setting errno=0 before the next call.
So errno keeps being EINTR, while "_c" already succeeds, and make run into an endless loop.
