# Make all files include "config.h" by default. This shouldn't cause any
# problems and we cannot forget to include it anymore.
#
# Also make the linker discard all unused symbols.
#
# When compiling in debug mode, we enable debug symbols so debugging with gdb
# is easier. If optimizations are disabled, we pass -O0 to the compiler.
# Otherwise, we use standard optimizations -O2.
