Re: [PATCH] put some support optional at configure time

[Sergey Poznyakoff]

Hello,

I have added the proposed --disable-[whatever] options to configure.
The --disable-mbox was not added because it would require a major
restructuring of the testsuite and a restructuring of mailbox as
well (parh_record is effectively an alias to mbox_record, etc...)
I'll be back on November, 4th, then I'll cope with this as well.

I've used a different approach, however. The main objectives for
this were:

  1) Moving duplicate code from configure.ac into a separate defun.
  2) Avoiding excessive use of #ifdef blocks in applications. When
     you compile the package with --disable-PROTO, the PROTO_record
     variable remains available (it points to NULL), so none of the
     existing applications have to be changed.
     The side effect of this is that the complication of
     mailbox/Makefile.am is avoided as well.
  3) The file_record and path_record should not be disabled along with
     mh_record as the proposed patch did. They have nothing to do with
     mh, they are associated with the mbox format.
  4) The proposed patch didn't take the testsuite into account.

Thank you.

Sergey
