Well you just need to run configure once, when you setup the building
tree!!
You certainly don't know what you are doing. The "make" command will
not track your compilation flags! You don't know what objects where
compiled using some CFLAGS if you just change them on the fly!! You
would need to "make clean" before changing the CFLAGS!!
How long does a "make clean && make" takes in this huge project of
yours? Probably you could save lots of time if you had two different
build trees!!
