Got it.
Thanks a lot

These test suite failures smell compiler bug.  Unfortunately, while
Apple is a large company, their compiler team does not seem to be able
to produce a robust compiler.  Only every few "Xcode" release comes with
a compiler which GMP does not trip up.

I haven't kept a list of versions of the compiler which does not work.
But I know for a fact that the first Xcode release which came with
Catalina did not.  The first update was no better, but I think the third
update actually worked.

You might want to install a new Xcode version.

See
https://gmplib.org/manual/Headers-and-Libraries.html#Headers-and-Libraries.

: Note however that prototypes for GMP functions with FILE * parameters
: are only provided if  is included too.

These two includes need to be in the opposite order.

gmp-6.1.2 Bug Report (gmp_fprintf(), "implicit declaration of function" warning)

[mlg .]

Long story short, with gcc, the function/macro "gmp_fprintf()" gives
an"implicit declaration of function" warning. Please see the attached file
for the complete report.

Best regards,
Miraç Lütfullah Gülgönül
GMP VERSION: gmp-6.1.2

TEST PROGRAM: 
#include 
#include 

int main() {
FILE *bug_file;
mpz_t bug;

mpz_init_set_ui(bug, 1);
bug_file = fopen("bugg.txt", "w+");
gmp_fprintf(bug_file, "%Zd\n", bug);
fclose(bug_file);
return 0;
}

DESCRIPTION:
Running the above code gives the following compiler warning:

In file included from bug.c:1:
bug.c: In function 'main':
/usr/local/include/gmp.h:534:21: warning: implicit declaration of function 
'__gmp_fprintf'; did you mean '__gmp_sprintf'? [-Wimplicit-function-declaration]
#define gmp_fprintf __gmp_fprintf
 ^
bug.c:10:5: note: in expansion of macro 'gmp_fprintf'
 gmp_fprintf(bug_file, "%Zd\n", bug);
 ^~~

So basically there is something wrong with the gmp_fprintf function/macro.
Note that the code runs just fine, since it is a warning only.

The GMP developers cannot handle Microsoft's proprietary file formats,
and thus cannot read your attachments.

Plain old text is what you need to send in your message and in your
attachments.  Make sure you spell out what you think it wrong, a bunch
of attachments (even readable ones) might not immediately reveal the
perceived problem.
