There are a couple of flags you can use to statically modify RIOT's behavior or to enable/disable certain features.

Usage Example:

QUIET=1 CFLAGS="-DSCHEDSTATISTICS -DDEVELHELP" make clean all

General

CFLAGS=-DSCHEDSTATISTICS - enable gathering and display of scheduler statistics
CFLAGS=-DDEVELHELP - enable certain code sections useful for development
CFLAGS=-DSCHED_TEST_STACK - enable (simple) testing for stack overflows
RIOT_VERSION=foo - build a tagged version of RIOT
RIOT_VERSION_OVERRIDE - override the version string - useful for comparing build sizes (available once https://github.com/RIOT-OS/RIOT/pull/3035 is merged)

Make Specific

QUIET=1 / QUIET=0 - enable/disable hiding of compiler invocations

Platform Specific

native

CFLAGS=-DNATIVE_AUTO_EXIT - terminate the native process after the last RIOT thread has exited.

Module Specific

transceiver

CFLAGS=-DDBG_IGNORE - enable the transceivers ignore command (useful for debugging)
