I have a submakefile for each platform, e.g.

  # in posix.makefile :
  EXEEXT :=
  # ... many other platform-specific definitions

  # in msw.makefile :
  EXEEXT := .exe

and I include the appropriate one based on 'uname':

  uname := $(shell uname -s 2>/dev/null)
  platform-makefile := posix.makefile
  ifeq (MINGW,$(findstring MINGW,$(uname)))
    platform-makefile := msw.makefile
  else
  [handle unames containing other strings like "CYGWIN" similarly]

  include $(src_dir)/$(platform-makefile)

If you use an msw platform that (unlike MinGW or cygwin) doesn't
provide 'uname', then you could write a script like

  #!/usr/bin/sh
  echo

for that platform, and treat it as a default case (empty result
from 'uname' implies msw).
