Re: undefined or invalid # directive (#import ...) when compiling coreba

Subject: Re: undefined or invalid # directive (#import ...) when compiling corebase with gcc-2.95

I ran into some extra time tonight and put something together.  Wasn't at all hard since I used NSByteOrder.h in base as a template.

The one thing I found weird is that none of the SwappedFloat functions in -base actually swap anything.  It seems like they just return the same value.  Richard, your name is on that file, can you confirm that that's correct?

I'm still not sure what to do with the CFRuntime issue.  Can anyone else suggest something?

Stef

No hurry at all!
I only promised to report potential problems or success, unfortunately I had to report problems.

yes, I guess that's the problem. IIRC, I've seen the problems with ... somewhere else too, with regard to gcc-2.95.

cheers,
