Eric,

The libbitcoin ./configure takes as "Some influential environment 
variables:", the "CC     C compiler command".

Just for clarity, "CXX"+"CXXFLAGS" is the only one that one that is
used, and "CC"+"CFLAGS" is NEVER ever used and will never be, in any
libbitcoin repo with the sole exception being the secp256k1 library,
right?

Thanks!
