This could usefully be combined with the nearby thread about recording
configuration options (started by Thomas).  I'd be inclined to make it
a low-footprint affair where you do something like
select compilation_options();

and you get back a long textual list of var=value settings, say

VERSION=7.3devel
PLATFORM=hppa-hp-hpux10.20, compiled by GCC 2.95.3
BLCKSZ=8192
MULTIBYTE=yes
etc etc etc etc

This would solve the diagnostic need as-is, and it doesn't seem
unreasonable to me to expect applications to look through the output
for a particular line if they need to get the state of a specific
configuration option.  It's also trivial to extend/modify as the set
of options changes over time.
