  Why not use AS_HELP_STRING here?

No good reason other than consistency in avoiding bugs: Autoconf-2.59's AS_HELP_STRING computes the number of characters wrongly in the presence of quadrigraphs, which was fixed in 2.60. Furthermore, AS_HELP_STRING still (in CVS Autoconf) does not cope well with commas in the strings, and one of the help strings in GCC's configure.ac uses a comma.

Cheers, Ralf
