[omniORB] unable to set correct path, VS7, XP

[Andrea L. Blackwell]

I am trying to run the omniorb examples(echo) but I am unable to get nmake
(cl.exe) to find the basic c header files (stddef.h, string.h, etc).  I am using
XP and have Visual Studio .NET 	7 installed.  I have added omni orb dlls to my
path, have cywin installed, and can generate the stubs.  However when I try to
build even the simplest of examples nmake fails for simple header files.  Is
there a kind soul who can direct me towards what I'm missing?  Anyone know what
specific visual studio files are needed in the path?
Thanks - ALB
