Thanks.  Actually, I haven't bothered to check if the value of
use_mmap_for_buffers has an effect when hybrid malloc is enabled, but
it's a clean-up at least and the configure summary would be misleading.

Thanks, this almost worked, I had just to double the static heap size.

In the ensuing successful build, I got the following message after
dumping:

18788992 of 33554432 static heap bytes used

However, this is with my standard configuration, which doesn't include
everything:

ssystem-configuration-features is a variable defined in ‘C source code’.
Its value is
"XPM JPEG TIFF GIF PNG IMAGEMAGICK SOUND NOTIFY ACL GNUTLS LIBXML2 FREETYPE
