[users@httpd] How to change compile-time constant

[Christopher R Newman <ch...@alcatel.com>]

Hey everyone,
    Is there a way to modify some environment variable or something to 
change compile-time constants?  If not and I have to recompile apache, 
can I safely do so without altering or losing any of the files I've 
added (cgi's, conf's, etc.).  I would like to change the compile-time 
constant while leaving everything else as intact as possible so the 
server won't be down long.
    One more question.  Can I disable the 
DEFAULT_LIMIT_REQUEST_FIELDSIZE or do I have to set it to a REALLY huge 
number?  I want to be able to modify the LimitRequestFieldsize directive 
so I can send lots of cookie info in the header.

Thanks in advance,
Chris
