Step 0) Note the warning about changing these settings in
/usr/share/examples/etc/make.conf and in the make.conf manpage.

Step 1) Revert those silly optimizations back to the default

Step 2) Rebuild everything to undo the damage

Well, in short, that worked. I have now build the kernel. I'm a little confused though and could use a bit of an explination.
 
 I thought only the COPTFLAGS options where used during kernel compilation and I had attempted to build with those commented out completely before. I can only guess that the CFLAGS are still in effect too.
 
 Now I have a custom kernel which is failing to build. I've attached the config file for it, and it fails trying to build with references about ieee80211. The odd thing is I have no wireless in my box and have commented out all the wireless references. What else is dependant on them and should be commented out as well? The last bit of output is below.
 
 Thanks again,
 Grant
