Comment (by jpflori):
The evilish `__imp` prefix is a Cygwin hack to link to DLL through static
import libraries.
The DLL exposes usual function names but might be problematic to directly
link to, and the static import library is... well... static and provides a
proxy to real function in the DLL, the proxy having the same name with
`__imp`prepended.
Note that it is not even needed anymore to go through static import
libraries to link to DLL's but it is common practice to produce them.
In the end the results is more or less the same performance wise for the
produced binaries which use the DLL although linking time is higher when
import libraries are used.
In case you want to link to directly object files together you definitely
don't need the `__imp` black magic.
Or so do I think.
