in libs built with binutils >=2.19. This is a less error-prone method than the previous where components had to be tagged in the Makefile as modules (and if they weren't, things broke. and vice versa).

# satisfied by the toolchain itself when the program is linked.

# Unfortunately, we do not know which of the symbols are generated by
|
|
# the toolchain. Worse, they vary from platform to platform and
|
|
# toolchain to toolchain. The good news, however, is that this will
|
|
# be detected by a compile-time failure, so we can fairly easily manage
