Compilation failing with --disable-builtin-tiff flag

[lexxer3d]

Compilation fails with this output:

gcc -o make_v34_convolutional_coders ../src/make_v34_convolutional_coders.c -DHAVE_CONFIG_H -I../src -lm
./make_v34_convolutional_coders >v34_convolutional_coders.h

In file included from ../src/make_v34_probe_signals.c:28:

      |          ^~~~~~~~~~
compilation terminated.
make[4]: *** [Makefile:1602: make_v34_probe_signals] Error 1

The issue is with make_v34_probe_signals.c that includes "spandsp.h" which, in turn, demands tiffio.h.
A trial solution is to replace spandsp.h with the following includes:

#include <inttypes.h>
#include <stdio.h>

// #include "spandsp.h"

#include <stdlib.h>
#include <math.h>
#include "spandsp/telephony.h"
#include "spandsp/bit_operations.h"
#include "spandsp/g711.h"

Also there's an issue in meteor-engine.c:979 with printf format missing a string parameter:

gcc -o make_v34_tx_pre_emphasis_filters ../src/make_v34_tx_pre_emphasis_filters.c ../tools/meteor-engine.c -DHAVE_CONFIG_H -I../src -I../tools -lm
../tools/meteor-engine.c: In function ‘vet_data’:
