By "current version" to you mean 1.2.1, or svn?

Hmmm...  We added ":=" to avoid recalculating lots of check_gcc() macros 
(which is PAINFULLY slow, and largely there so Bernhard can keep an old Tru64 
system upright through various necromantic rituals).  Unfortunately, this is 
overriding anything provided in environment variables, isn't it?

Probably the easy thing to do at the moment is search for CFLAGS:= in 
Rules.mak (line 55 in my copy) and add your flags there.  This sucks as a 
solution, anybody else got a better suggestion?

Makefiles are evil.  I am _so_ glad this is not my problem anymore.  Denis 
replaced this mess entirely, which means they'll be re-fixing old bugs for a 
while but hopefully have a better general infrastructure now...
