@NAME : btparse.h
@DESCRIPTION: Declarations and types for users of the btparse library.
(Actually, btparse.h is generated from btparse.h.in by
the `configure' script, in order to automatically determine
the appropriate values of HAVE_USHORT and HAVE_BOOLEAN.)

* includes pccts/ast.c) crashes because of this (yes, yes, I know it
* should just be a warning -- I don't know what's going on there!).
*
* Unfortunately, this duplicates code in bt_config.h -- I can't include
* bt_config.h here, because this header must be freestanding; I don't want
* to include bt_config.h in pccts/ast.c, because I don't want to touch the
* PCCTS code if I can help it; but I don't want every source file that
* uses strdup() to have to include btparse.h. Hence the duplication.
