Oh yes, this is an example

make[2]: ingresso nella directory "/tmp/work/emacs-master/lib"
  CC       acl-errno-valid.o
  CCLD     ddeclient.exe
In file included from ../src/conf_post.h:32:0,

                 from ../src/config.h:1926,

                 from acl-errno-valid.c:20:

C:/msys64/tmp/work/emacs-master/nt/inc/ms-w32.h:296:17: warning: 
conflicting types for built-in function 'execve'

 extern intptr_t execve (const char *, char * const *, char * const *);

                 ^~~~~~

  CCLD     runemacs.exe
make[1]: uscita dalla directory "/tmp/work/emacs-master/nt"



The header ms-w32.h is included elsewhere and gives 134 of this warnings..
