# CFLAGS controls the compiler settings used when compiling C code.

# nonstandard optimization settings

# Compiling with -fstrict-aliasing optimization breaks some [notable] ports.
# GCC turns on -fstrict-aliasing optimization at all levels above -O[1], so
# explicitly turn it off when using compiling with the -O2 optimization level.

# Additional compiler flags can be specified that extend or override
