I've always been strongly opposed to  "every platform should have its own
implementation", since it tends to violate DRY for insufficient
justification.  I would (heretically!) like Java more if there were more
facilities for writing a single source file targeting slightly different
platforms.

 ifeq ($(OPENJDK_TARGET_OS_API),posix)
-    UPSUFFIX:=$(OPENJDK_TARGET_OS)
-    ifeq ($(OPENJDK_TARGET_OS),macosx)
-        UPSUFFIX:=bsd
+    UPSUFFIX:=posix
+    ifeq ($(OPENJDK_TARGET_OS),solaris)
+        UPSUFFIX:=solaris
     endif


I'm inclined to structure things as in the other makefile

if solaris

  solaris code here...

else

  general unix code here ...

endif
