raze/polymer/eduke32/Makefile.common
helixhorned 57dbedf59d Makefile.common: add a couple of C warning flags.
Most notably, -Wdeclaration-after-statement.  This and -Wpointer-arith
give some warning on linux, but this is "harmless" as it's assumed that
we'll be always compiling with GCC or Clang there.

Also, erratum in the "Make ksqrt take uint32_t ..." commit:
 hypotenuse -> squared length of the hypotenuse
