I was able to compiled the gateway but I got the error below running the make command.

This error comes when you're compiling with mysql 8
To fix this, add these lines to gwlib/dbpool_mysql.c
/* define my_bool for newer versions because they use the bool or int C type instead */
#if MYSQL_VERSION_ID >= 80000 && !defined(MARIADB_BASE_VERSION)

This is quite similar to GCC define function-like macros using -D argument but I couldn't find a relation to my use case.
Consider the following code, main.c:
#include <stdio.h>
const char greeting[] = "hello world";
//#define printf(fmt, ...) (0)
int main() {
printf("%s!\n", greeting);
return 0;
}
If I compile and run this, it works as expected:
$ gcc -Wall -g main.c -o main.exe
$ ./main.exe
hello world!
$
Ok, now I want to How to disable printf function? so I uncomment the #define in the code; I get some warnings, but things again work as as expected (as there is no printout):
$ gcc -Wall -g main.c -o main.exe
main.c: In function 'main':
main.c:5:26: warning: statement with no effect [-Wunused-value]
5 | #define printf(fmt, ...) (0)
| ^
main.c:8:5: note: in expansion of macro 'printf'
8 | printf("%s!\n", greeting);
| ^~~~~~
$ ./main.exe
$
Now, go back to the example as originally posted - that is, comment the #define like - and let's try to set that define via the command-line -D argument:
$ gcc -Wall -D'printf(fmt, ...)=(0)' -g main.c -o main.exe
<command-line>: error: expected identifier or '(' before numeric constant
main.c: In function 'main':
<command-line>: warning: statement with no effect [-Wunused-value]
main.c:8:5: note: in expansion of macro 'printf'
8 | printf("%s!\n", greeting);
| ^~~~~~
Well, the command line argument -D'printf(fmt, ...)=(0)' causes the compilation to fail.
Is there any way I can format this macro somehow, so I can set it via the gcc command line using the -D argument? (Bonus: can it be formulated somehow, so it does not raise warnings like "statement with no effect")
EDIT: contents of C:/msys64/mingw64/include/stdio.h lines 366 to 372:
366 __mingw_ovr
367 __attribute__((__format__ (gnu_printf, 1, 2))) __MINGW_ATTRIB_NONNULL(1)
368 int printf (const char *__format, ...)
369 {
370 int __retval;
371 __builtin_va_list __local_argv; __builtin_va_start( __local_argv, __format );
372 __retval = __mingw_vfprintf( stdout, __format, __local_argv );
373 __builtin_va_end( __local_argv );
374 return __retval;
375 }
When you use:
#define printf(fmt, ...) (0)
The preprocessor turns the code into this:
int main() {
(0);
return 0;
}
That free standing (0) is not allowed. However if you define it this way:
#define printf(fmt, ...)
You can also use the command line definition:
"-Dprintf(fmt, ...)="
Everything works.

Digging a bit more I found that I could try to add
#include <string>
#include <cstring>
to the header zlib.h but this does not work either.
What else can I do to solve this issue?.
I'm trying to compile GCC 4.7.2 on a Buffalo LinkStation Pro Duo (after unlocking it) which runs Linux 2.6.31.8 armv5tel.
Unfortunately, make throws quite some errors, starting with

Following this post I seem to have forgotten to install ppl, which I'll try now
SIZEOF_LONG should be #defined by configure in the file auto-host.h. Your auto-host.h should contain something like:
/* The size of `long', as computed by sizeof. */
#ifndef USED_FOR_TARGET
#define SIZEOF_LONG 8
#endif
If the above is not present (and it looks like in your case it's indeed so), check config.log for errors. Search for errors around the string checking size of long.
Thanks to chill's answer I checked config.log to discover
conftest.c:10:19: error: ppl_c.h: No such file or directory
(which, curiously, did not prevent configure from creating a Makefile and returning a success error code). The first google hit on that was this post, showing I didn't provide the ppl dependency.
The ppl-1.0 compilation greeted me with
checked_float.inlines.hh:1012: error: 'frexpl' was not declared in this scope
which led me to this post suggesting I'd use the 1.1 snapshot instead, which worked
Now, gcc's make offered me another "helpful" error:
gcc/../libcpp/include/line-map.h:66: error: 'CHAR_BIT'
which turned out to be due to C_INCLUDE_PATH ending with a colon (I already experienced the checking LIBRARY_PATH variable... contains current directory error mentioned in that post, but didn't think about checking other variables for that as well)
Compilation is still running, so far no more errors...
