I am starting to think that strict will cause too many problems :-(

*** omake error:
    File lib\build\C.om: line 166, characters 1-38
    Do not know how to build "c:\Program Files\Microsoft Visual Studio 
.NET 2003\VC7\PlatformSDK\include\rpcdcep.h" required for 
"src\clib\lm_notify.obj"

(the real file name is RpcDceP.h, but the C scanner prints all the 
header files in lowercase).

This is probably the way to go. Except, we might want to try adding some 
code to "inherit" the real case through the implicit rules.

The issue is that we'd also have to have the notion of a "realpath" for 
any "future" targets that we are planning to build in order for this to 
do what we want.
