Was this the error?

c++ -Wall -DHAVE_CONFIG_H -Wno-unused -c grap_lex.cc
c++ -Wall -DHAVE_CONFIG_H  grap.o grap_lex.o grap_draw.o grap_pic.o
grap_parse.o
 grap_tokenizer.o   -o grap
grap_lex.o(.text+0x6630):grap_lex.cc: undefined reference to `errno'
collect2: ld returned 1 exit status
make: *** [grap] Error 1

If so, and nothing else amiss, then it will link if you insert...
#include <errno.h>
...into grap_lex.cc just after <stdio.h> (line 9)...

<snippet>
#define FLEX_SCANNER
#define YY_FLEX_MAJOR_VERSION 2
#define YY_FLEX_MINOR_VERSION 5

#include <stdio.h>
#include <errno.h>	// <-insert
</snippet>

..then make again.
