I agree.  I just wanted to note that I looked at this -ldl stuff once 
upon a time, and the verdict was, it's not supposed to even be there on 
Cygwin.  CMake tests for both the header and the library, and does the 
right thing.

There is no notion of "Debug" vs. "Release" when building with GCC.  
There are only static vs. dynamic libraries and exes, all of 'em 
optimized, none of 'em debuggable.

On MSVC we've got Debug, Release, MinSizeRel, and RelWithDebInfo.  I'll 
look up appropriate flags for these; I don't think -fomit-frame-pointer 
is the lingo.

I'll have to ask on the CMake list about this.  If we wanted to ship 
*only* MinSizeRel, then it seems we (SET CMAKE_BUILD_TYPE 
RelWithDebInfo).  But if we want to ship all 4 built types, as is 
currently done, then I don't see an interface to select the default.  
The default is "Debug" and I don't know if that can be changed.
