That's nice! :-) I will add this as a config option, and crosstool-NG will
set it if asked for.

2.18.50.0.8 works around the shell not having the BASH_LINENO variable by not
using it at all, and thus not storing the correct lineno in the generated
files. The fix is not needed, at the expense of a little less info. This can
nonetheless be improved upon...

(*)Whoo! :-)

(*) Bah I just upgraded my machine so that I don't wait to long for the builds
    to complete: compile time was divided by about 7. GMP takes only 35" and
    MPFR 33", now (with checking)! :-]
YEM.
