It is defined for all platforms when math.h or cmath is included
after defining the macro _USE_MATH_DEFINES.
Define _USE_MATH_DEFINES before any include statement to make sure
that M_PI gets defined. It is not necessary to define it conditionally
only for Windows.

Void functions should not use @return. It causes compiler warnings
like this one:
src/classify/intproto.cpp:326:5: warning:
'@return' command used in a comment that is attached to a function
returning void [-Wdocumentation]
Some non-void functions also were documented with @return none.
Fix those comments, too.

Remove unneeded include statements, remove conditional statements and
replace the remaining assert.h by their standard C++ variant cassert.
