Well, how is this done?

If I use: 'gcc -o foo foo.o'
Returns: foo.o(.text+0x1b):foo.c: undefined reference to
`_imp__SetupDiGetClassDevsA AT 16'

If I use: 'gcc -o foo foo.o setupapi.lib'
Returns the same

If I use: 'gcc -o foo foo.o -L. -lsetupapi.lib'
Returns unknown library 'setupapi.lib'

If I rename setupapi.lib to libsetupapi.a and run 'gcc -o
foo -L. -lsetupapi'
Returns unknown library.

This is all caused (I think) by the missing symbols, which are found in the
public setupapi.dll file. And my question boils down to this: How do I
include a dll file like this into my application from GNU tools?
