According to Andreas Koenig*, under NeXTstep 3.2, both perl4.036 and perl5.000 compile with the supplied hints file.
However, Bill Eldridge* provides this message to help get perl4.036 on NeXTstep 3.0 to work:
To get perl to compile on NeXTs, you need to combine the ANSI and BSD headers:cd /usr/include mkdir ansibsd cd ansibsd ln -s ../ansi ln -s ../bsdThen, follow the configuration instructions for NeXTs, replacing all mention of -I/usr/include/ansi or -I/usr/include/bsd with -I/usr/include/ansibsd.
