Yes, this problem seems to occur only on platforms where realloc(NULL,size)
is not the same as malloc(size), such as SunOS 4.1.x.  I've incorporated
your suggested fix, which will be in the next beta.  Thanks for being
persistent and reporting the problem again.

ncgentab.c contains the lines

    /* get lexical input routine generated by lex  */
    #include "ncgenyy.c"

and ncgenyy.c (generated by lex from ncgen.l) contains the needed STREQ
definition.

This builds with no problem on our AIX 4.1 system.  My guess is that the new
distribution might have been unpacked on top of an old distribution, so that
an old version of ncgenyy.c was used instead of a new ncgenyy.c built by lex
from ncgen.l.  If you do a

        make clean all test

in the ncgen directory everything should work, because lex will regenerate
ncgenyy.c.  If that doesn't fix the problem, please let us know.
