Description:It seems that at least in dahdi-tools 2.0.0 libtonezone depends on libm . Hence the configure script failes to detect it, as we get link failures with 'pow', 'cos' and others missing.

Tested with 1.6.0.1 , but from a quick look I don't think this has been resolved in trunk yet.

Note that this is only a problem if you use a statically-built libtonezone.

However: I don't think static libraries make any sense in an environment like Asterisk, where you dynamically load modules.

Sometimes even Linux needs -lm to link libtonezone, such as when libtonezone
is compiled statically.
