+ * The include file compat/bswap.h has been updated so that it is safe
+ to (accidentally) include it more than once.
+ (merge 33aa579a55 jk/guard-bswap-header later to maint).
+
+ * The set of header files used by "make hdr-check" unconditionally
+ included sha256/gcrypt.h, even when it is not used, causing the
+ make target to fail. We now skip it when GCRYPT_SHA256 is not in
+ use.
+ (merge f23aa18e7f rj/hdr-check-gcrypt-fix later to maint).
+
+ * The Makefile uses 'find' utility to enumerate all the *.h header
+ files, which is expensive on platforms with slow filesystems; it
+ now optionally uses "ls-files" if working within a repository,
+ which is a trick similar to how all sources are enumerated to run
+ ETAGS on.
