With libc++ 19, biology/biosig fails to compile, with errors similar to:
/usr/include/c++/v1/__math/special_functions.h:51:16: error: expected unqualified-id
51 | if (!__math::isfinite(__H_n)) {
| ^
./t230/../biosig-dev.h:932:22: note: expanded from macro 'isfinite'
932 | # define isfinite(a) (-INFINITY < (a) && (a) < INFINITY)
| ^
This is because biosig attempts to define its own isfinite() macro,
which it should not do. Stub out the incompatible definition.
