I am having trouble building GDB 4.1 on a 386 running Interactive Unix
2.2 (a SYSV3.2 variant).  I ran into these problems (and probably
others which I have forgotten):

1) The Makefile tried to use cc which failed right away so I switch it
   to gcc.
2) gcc defines __STDC__ which causes <sys/stat.h> to complain about
   not knowing about the typedef mode_t.  (Will -DPOSIX_SOURCE fix
   this?)
3) We don't know about tchars.  (I has to define TIOCGETC_BROKEN.)
4) One file needed <sys/types.h>
5) One file used O_NDELAY instead of O_NONBLOCK.
6) One file referred to u.u_fpstate.  We have u.u_fps.u_fpstate.
7) One file didn't include <sys/signal.h> but included <sys/user.h>
   thus MAXSIG was undefined.
8) One file thought that I didn't have strstr and tried to include one
   which conflicted with the definition on strstr in a system include
   file.
9) Some files included memory.h and strings.h.  The definition of the
   memory functions in memory.h conflicted with the definition in
   strings.h.
10) sh complained about the define "-Dgetpagesize()=4096" in the
    Makefile.  I quoted out the parens and then gcc complained about
    the define.
11) (And this is where I am stuck.) I got several undefined symbols
    when I tried to link.  Specifically:
undefined			first referenced
 symbol  			    in file
fileno                              main.o
putc                                breakpoint.o
strstr                              source.o
getc                                source.o
have_inferior_p                     i386-xdep.o
corechan                            i386-xdep.o
ieee_double_to_extended             i387-tdep.o
getpagesize                         gmalloc.o
sigsetmask                          ./../readline/libreadline.a

I can find putc and getc in libcposix.a.  I may be able to find
strstr.  I am confused about the others.

Has anyone got gdb to compile under Interactive Unix 2.2?  Should I
try -traditional switch on gcc?  Any other ideas?

Thanks.
