compiler errors, include paths, and gnatreg

Thanks for reading

I've finished my first year studying ada at my university and enjoyed
every second of it.  My problem is that I have a lot of questions and
I'm not around my teachers to get them answered.

I'm trying to compile the examples sent with AdaSockets v0.1.19 for
Windows.  I want to do this by running make.bat but when i do i get
pagers of errors that say something like
compiling.error: "sockets-thin.adb" and "tcprelay.adb" compiled with
different GNAT versions
and stuff like this
error: "s-stalib.adb" must be recompiled ("a-except.ads" has been
modified)

It says that i need to change my ADA_INCLUDE_PATH and ADA_OBJECTS_PATH
environment variables to point to the adapower directory, but i don't
know how to do this.

and it says i can use gnatreg to do that too, but i don't understand
what that utility does?

Can anyone answer my questions?  thanks a lot!

Sincerely,
Aaron W. Myers
