#
# 3 proxy Makefile for GCC/Linux/Cygwin
#
# add -DWITH_ODBC to CFLAGS and -lodbc to LIBS to compile with ODBC
# library support. Add -DSAFESQL for poorely written ODBC library / drivers.
#
# Linux splice() support is not built by default, it is slower than the
# read/write path for most traffic. Add -DWITHSPLICE to CFLAGS to build it,
# it must additionally be enabled per service with the -s option.
