Subject BASE et.al. and DLL relinking on W32
Date Sat, 11 Jul 1998 17:26:18 GMT

thanks Jon.  I recall two additional things though.  A tool
that if applied at install time will assure no conflicts
on load, and a scheme that marks each DLL's with it's required
DLLs in a manner that allows the dynamic loader to know that
it doesn't have to worry AT ALL, and can just mmap the pages
and be done with it.  I stumbled on this by dumping the DLL's
using some dump tool and noticing that the OS DLL's have thier
required DLL's marked up with date stamps, but my DLLs didn't.
