"; if ${T}/nptl; then return 0; else return 1; fi; else echo "no"; fi; return 1 } I'm guessing which is just hunting for the function definition '^[^ ] \(\)[[:space:]]{\n', and then matching till '^}$', which isn't valid (or at least is an unexepected 'feature'). Work around is type has_NPTL which has it's own issues in isolating the function.
Haven't tested it w/ v2.12, but 2.16 I've verified as failing.
e-mailed upstream ... the problem lays in the code block in which.c around line ~550
bugs going no where, wrote filter-env to get around this...
