# CCFLAGS must be taken from the flags used to compile libmysqld. The reason for that is that if the flags are not
# identical, the THD class behaves differently in libmysqld than it does in my_parse_cc.cc, namely, the thd->command
# member is located in a different place in memory. No attempt was made to determine which compile flag causes this behavoir.
#
# Also, if we compile our stuff with DDEBUG and libmysqld.so is not compiled with DDEBUG, crap will result.
