I tried your suggestion below, but it does not store the options unless 
the -g option is used.

If -g is used, the executable _always_ has version and option info (no 
extra code invoking compiler_version() and compiler_options() is 
needed). Just use strings <binary> | grep GNU .
If -g is not used, no option info is in the executable.

Best wishes,
Kay
