things that fail to build with gcc and libobjc2

[Sebastian Reitenbach]

Hi,

I recompiled everything yesterday with gcc 4.2.1 and without libobjc2. For 
some of the stuff in the list I sent in the other thread, I have taken it from 
svn/cvs since the last releases available releases did not compiled. 
Everything compiled with it with the new gnustep core from svn.

Now I tried again to build everything with gcc again, but with libobjc2. The 
success rate is unfortunately not at 100%.

SOPE 1.3.4 (1.3.6 will be released probably this week, so still have to test 
newer version, but I guess there is not much changed in this file) fails to 
compile this way:

for example, line 118 looks like this:
static void
fillMethodListWithSpecs(MethodList_t methods, SEL _selector, va_list *va) 
{
  /* takes triple: SEL, signature, IMP */
  SEL      selector;
  NSString *signature;
  IMP      imp;
  unsigned count;

  selector  = _selector;
  signature = selector  ? va_arg(*va, NSString *) : (NSString *)nil;
  imp       = signature ? va_arg(*va, IMP) : NULL;
  count     = 0;
  while ((selector != NULL) && (signature != nil) && (imp != NULL)) {
    unsigned   len;
    char       *types;
#if GNU_RUNTIME
    const char *selname;
#endif
