WHAT'S NEW with version 0.0.2:
- Again thanks to Eric Youngdale for some very useful comments.
- The Windows startup code created by Micrsoft C 7.0 now runs
to completion.
- Added a new patch to the kernel to increase the usable size of
the ldt to the full 32 entries currently allowed.
- Imported name relocations are now supported.
- Source code for my infamous test program is now included.
- A handful of basic Windows functions are now emulated. See
"kernel.spec" for examples of how to use the build program.
WHAT'S NEW with version 0.0.1:
- Eric Youngdale contributed countless improvements in memory
efficiency, bug fixes, and relocation.
- The build program has been completed. It now lets you specify
how the main DLL entry point should interface to your emulation
library routines. A brief description of how to build these
specifications is included in the file "build-spec.txt".
- The code to dispatch builtin DLL calls is complete, but untested.
