Tests failing in GCC - macos

I'm starting to work with GCC. I downloaded the 4.4.2_release in Mac OSX and I'm running the tests through "make check-gcc" and many tests are failing, I thought that all tests of the test suite in a stable release should pass... so I have some questions:
Is it normal? Or maybe I've done something wrong?
Is there any default configuration that I can use for all the tests pass?
Thanks,
Adding more information requested:
This is the command line I used:
make check-gcc RUNTESTFLAGS="dg.exp"
Here is the summary of the results:
=== gcc Summary ===
expected passes 9265
unexpected failures 1700
unexpected successes 6
expected failures 66
unresolved testcases 45
unsupported tests 93
Here are some examples of the tests that are failing, from log file:

I'm using Windows 10, Kotlin Native Windows 1.4.21.
It works fine in Mac.
Thank you.

As we figured at the https://youtrack.jetbrains.com/issue/KT-44049, the problem was in the incorrect archive being downloaded.
This document mentions downloading kotlin-compiler-1.4.21.zip, while you have probably downloaded kotlin-native-prebuilt-windows-1.4.21.zip

Prolog natural language parser, Arguments are not sufficiently instantiated

i am trying to make a prolog language parser. when i go to load my script my get the error
ERROR: Arguments are not sufficiently instantiated
ERROR: In:
ERROR: [13] throw(error(instantiation_error,_1940))
ERROR: [7] <user>
ERROR:
ERROR: Note: some frames are missing due to last-call optimization.
ERROR: Re-run your program in debug mode (:- debug.) to get more detail.
my code is as follows
sentence(Sentence,sentence(np(Noun_Phrase),vp(Verb_Phrase))):-
np(Sentence,Noun_Phrase,Rem),
vp(Rem,Verb_Phrase,[]).
np([X|T],np(det(X),NP2),Rem):-
det(X),
np2(T,NP2,Rem).
np(Sentence,Parse,Rem):- np2(Sentence,Parse,Rem).
np(Sentence,np(NP,PP),Rem):-

det(the).
noun(cat).
noun(mat).
verb(sat).
prep(on).
adj(big).
adj(fat).
adj(comfy).
i have read through some of the other posts on this but im still not sure where i have gone wrong.
to check that np pp and vp work i am using the calls; np([the,cat,sat,on,the,mat],O,L). , pp([on,the,mat],P,L). and vp([the,cat,sat,on,the,mat],O,L).. one call the error ERROR: Undefined procedure: vp/3 (DWIM could not correct goal) appears, it is the same error for all 3 calls with the only difference being vp/3 is either np/3 or pp/3
the desired goal is to use the call sentence(some_sentence) and have the program output the results of np pp and vp.

Am i missing anything? The configuration command used is:
./configure -debug -opensource -confirm-license -arch "x86_64" -cocoa -qpa
and I have Xcode Mac base SDKs for 10.7 and 10.8.

QPA is Qt platform abstraction, wherein you can develop your own plugin for embedded systems. It basically replaces the platform port.
QPA is well developed in QT5, maybe you can consider using it.
You need to resolve these compilation issues on your own and if you are planning on how to use QPA, minimal plugin is the best choice.
You can resolve these issues, basically by including ApplicationService framework and header. Hope this helps.

Use .conf.macosx instead of configure;
Open conf.macosx and add line: --with-x11;
Run:
sh .conf.macosx
Run:
make

I did a lot of googling for help, in vain. Can someone please help me with this?

It looks like it's the order in which files are included. See this page, which I found via google.
