Attaching an image is poor use of bandwidth (the mail server has to 
replicate the image to every subscriber, and some subscribers may have 
data limits that make downloading an image expensive); if an image is 
needed, it is better to just post a URL to the image hosted elsewhere 
(then only interested subscribers have to chase the link), or even 
better to just paste the text from your terminal instead of relying on a 
screenshot.

Transcribing relevant portions of what I see in the image:

$ make
C:/Apache/Git/mingw64/bin/make.exe  all-recursive
...
make[2]: Entering directory 'C:/Apache/httpd-2.4.41//srclib/m4-1.4.18/lib'

I haven't personally tried to build m4 under mingw, so it could be 
something about the mingw platform that is tripping you up (perhaps a 
stray carriage return somewhere confusing sh?).  So I'm not sure how 
best to proceed with debugging this build failure further.  The problem 
is probably not in math.h directly, but in the Makefile and shell code 
injected by gnulib's math module during autoconf/automake.  Perhaps you 
can try to find what portion of the generated 'configure' file is 
probing for math.h, or what gets inserted into the Makefile at the point 
where make tries to run /usr/bin/sh -c on a sed script that would 
generate math.h.
