# Compiler flags. The CPPFLAGS values should not include package debug

# `--enable-debug' switch of configure.  After titan's ecc was updated to 7.1,
# int64_t couldn't be found because of overlapping definitions in stdint.h
# and sys/types.h.  So added -D__GNUC__ to CFLAGS. (This problem is no longer
# there since the C library has been updated.  So -D__GNUC__ has been taken
