How is cygwin1.dll linked in?

[Kacvinsky, Tom]

I built the base Cygwin (really, just cygwin1.dll` and then went to compile
a test problem.  I did not see an import library for cygwin1.dll. so I am of
the opinion there is "magic" for doing this.  Is that magic the .idata section?
I _think_ the .data section is what passed on imported functions to the DLL
and adds it to the run time dependencies of the executable, but I am not
sure of this.

Any help on this matter would be appreciated.
