Re: [Gcl-devel] Re: OpenBSD and GCL

[Camm Maguire]

Greetings!  Yes the tools can be reworked somewhat.  But the big
problem is sbrk, which doesn't appear to work at all on openbsd.
Magnus, I just thought I'd mention that if this is unchangeably the
case, sbrk can be emulated.  You might want to take a look at the
macosx files for an example of this.  Perhaps you would know how to
construct an openbsd analog?

Take care,
