Hi,
building on cygwin: sice the default runtime appears to be broken, I got
current libobjc2, installed it an reconfigured base. I have a failure

any clues?
The problem here is that dladdr wasn't detected on your system. You
should check the config.log file to find out why this happened. GNUstep
will then fall back to a very old version of GSPrivateSymbolPath and
this uses Category. (Actually it doesn't as all the callers put in a
category of NULL) In libobjc2 this structure has been removed and there
is only a place holder declaration in GSProvate.h to make up for it.
This will allow the structure to be used as a parameter, but not to have
it accessed.
What you need to do is find out why you ended up in this old code path.
If dladdr isn't supported on Cygwin you could try to enable the MinGW
code path there as well.
