wdsp @20191111-e1926b68: error: redefinition of typedef ‘complex’

[ryandesign (Ryan Carsten Schmidt)]

​wdsp doesn't build, at least not on Snow Leopard:

This log shows that there are several other problems as well: it isn't UsingTheRightCompiler nor -arch (the makefile 1.0 portgroup might be used to fix that) and it's including nonexistent directories /include and /include/linux which it should not do.

Type redefinitions aren't permitted by the old gcc 4 on Snow Leopard and ideally projects wouldn't redefine types. But the log shows MacPorts wanted the port to build with clang 9. Once the port is fixed so that it is UsingTheRightCompiler the type redefinition complaint should go away.
