Windowing system distributor 'Apple', version 10.3.2113
System Description: macOS 12.6
This is latest master as of writing this. When compiling emacs, I see
emacs.c:899:7: warning: variable 'bufsize' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
if (!(emacs_executable && *emacs_executable))
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
emacs.c:964:7: note: uninitialized use occurs here
if (bufsize < needed)
^~~~~~~
emacs.c:899:3: note: remove the 'if' if its condition is always false
if (!(emacs_executable && *emacs_executable))
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
emacs.c:928:3: note: variable 'bufsize' is declared here
ptrdiff_t bufsize = exenamelen + strlen (suffix) + 1;
^
emacs.c:1755:17: warning: 'fork' is deprecated: Use posix_spawn or fork [-Wdeprecated-declarations]
