I just finished compiling perl on an IRIS, 3.3.  For anyone else who has
had problems, I offer these tips for perl version 4 patch 3 ...

<As a review, I'll repeat C. Harald Koch's (chk@alias.com) tips presented 
earilier.>

Add -D_BSD_COMPAT to the compiler options in Configure.

In config.sh, set the following variables to 'undef',
d_volatile='undef'
d_memcmp='undef'
d_vfork='undef'

The program compiles (kind of, see below), but fails two tests:
comp/decl......FAILED on test 7
op/write.......FAILED on test 1

I was getting unusual errors from the compiler, but not serious enough
for the compiler to stop.  The following is typical of the errors I was 
getting:

        cc -c -DTAINT `sh cflags.SH ttoke.o` ttoke.c
          CFLAGS =  -Uf_next -I/usr/include/sun -I/usr/include/bsd -D_BSD_COMPATccom: Warning: ttoke.c, line 2333: illegal member use: f_up
                return froot.   f_up.f_unext;
      -----------------------------^

Note the original line in the file is:

                return froot.f_next;

In <sys/file.c>, f_next was defined to be f_up.f_unext, which I guess was 
bad, because I did the following fix, and the problem went away.

Edit toke.c, and add the following line after all the other include statements:

#undef f_next

Now,
All tests successful.
u=0.63  s=1.9  cu=4.22  cs=6.15

Hope this helps,
