I don't think this should bother you, since Makefile uses $(CC), and
you can always invoke "make CC=<whatever>".

If so, then all you need is to say

  CONFIG_SHELL=a-Shell ./configure

and that should work.

So this Clang installation doesn't support the Standard C setjmp
function?  If so, you'd need to hack it out of the sources, e.g. by
defining it as a no-op.  It is not used for anything very important in
Gawk.

If you'd rather I keep silent because I cannot try this myself, just
say so.  I thought that by giving you some ideas I could help at least
some, seeing as no one else seems to chime in.
