 ACE_TEMPLATES_REQUIRE_SOURCE		Compiler's template mechanim must see source code (i.e., .cpp files).  This is used for GNU G++.
 ACE_HAS_EXPLICIT_TEMPLATES_INSTANTIATION Compiler's template instantiation mechanism supports the use of explicit C++ specializations for all used templates. This is also used for GNU G++ if you don't use the "repo" patches.
 ACE_HAS_TEMPLATE_INSTANTIATION_PRAGMA   Compiler's template instantiation mechanism supports the use of "#pragma instantiate".  Edison Design Group compilers, e.g., SGI C++ and Green Hills 1.8.8 and later, support this.
+ACE_REQUIRES_FUNC_DEFINITIONS           Compiler requires a definition for a "hidden" function, e.g., a private, unimplemented copy constructor or assignment operator.  The SGI C++ compiler needs this, in template classes, with ACE_HAS_TEMPLATE_INSTANTIATION_PRAGMA.
 ACE_USE_POLL				Use the poll() event demultiplexor rather than select().
 ACE_USES_ASM_SYMBOL_IN_DLSYM		Platform uses assembly symbols instead of C symbols in dlsym()
 ACE_WSOCK_VERSION 			A parameter list indicating the version of WinSock (e.g., "1, 1" is version 1.1).
