This sounds like you did not compile GNUstep with a compiler with blocks 
support (which also means that you will get exciting things happening if you 
try subclassing NSRegularExpression).  In this case, GNUstep will fall back to 
defining the block type as a struct and doing some hackery to invoke the block.

Try adding -fblocks to the CFLAGS your GNUstep install.  This is default on 
*BSD, but not on some other operating systems.  It should be implicit if you 
are using the GNU runtime and specify the non-fragile ABI though, so the fact 
that it isn't implies that yo are using the fragile ABI (which I would 
recommend against).  Try specifying --disable-mixed-abi (or something like 
that, try --help to find the correct option) to configure for base.
