Perhaps add a copy of allprint, without the character counting, to replace the existing extern declaration in your ncform, still #ifdef'd with LEXDEBUG. The signature of allprint should also be static void allprint(Uchar) and the exotic initial lines of sub1.c's allprint can be removed. It needs a #include <ctype.h> inside the #ifdef to get isprint.
Originally on Unix there was a separate little lex library with its own version of allprint.
