Bugzilla Bug 51525

a bug in the argument processing of 'bc' (v1.06) prevents it from properly
reading long-format options.  compare short opt "-l" versus long opt
"--mathlib" for example.  the patch below should fix it.  a spelling error has
been fixed as well.  i've submitted this patch to the bc author (over a year
ago), but the bug persists, so i hope we can at least work it out of the gentoo
distribution.

thanks,
shac ron.
