I got the source for flex and bison off of sumex recently and last night
decided to try porting them since they are both MPW C (by the way, if anyone
else has already ported them and would like to save me the trouble, I would
be greatly obliged, assuming that that is not the case ...).  I've run into
some slight difficulties and maybe a more major one.

Small problem #1: I get link errors with undefined bzero and mktemp.  I know 
that there is a PD C version of bzero floating around and I will try to find 
that, what about mktemp?

Small problem #2: alloca.  There are two assembler versions of this included,
but I don't have an assembler at present.  Having never used the TC inline
assembler, how difficult would it be to take one of these assembly sources
and produce something that TC could handle?  Should I not bother?  Is there
a C version that (while perhaps slower) is useable.

Bigger problem (and petty gripe):  (Before I even start, let me say that I
really like TC and I think the Symantec folks have done a great job, I've
been drooling all over the class library chapters of the manual, but haven't
had much time to play with it yet).  The ever-present and truly obnoxious
data segment too big error (32K limit on data segment size).  I don't want
to make wholesale changes to the code, is there an easy workaround for this?
What did MPW do, since this code apparently compiles there without problem?

On another (related to #2 note):  Is it possible to link MPW .o files into
TC applications?  There was a gnufuncts.o included somewhere, which would
probably take care of at least #2 and maybe #1.  I will admit that I did not
RTFM here, my first thought was oConv, but it didn't recognize the .o file.
Since I am doing this for my own use and my employer is keeping me pretty
busy these days, I don't have the luxury of spending a lot of my own time
figuring this out just now.  Any help would be greatly appreciated.  E-mail
to me and I will summarize to the net.  Thanx in advance.
