Tarball with reproducer of wine 11.19 loader source
Commit of discussion:
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=99600a4787910d4b1994b243473a7386dbee641d
Prior to binutils 2.47, Wine (https://www.winehq.org/) could link its
"wine-preloader" binary with its default arguments. Starting with 2.47 the link
now fails.
binutils 2.47 output:
gcc -m64 -o loader/wine-preloader loader/preloader.o loader/preloader_mac.o

I will attach the Wine 11.19 (latest as of today) loader code setup to build in
a small reproducer so you do not have to compile the entire project.
Note: The person who helped me discover this issue was the original commit
author, Nick.
Is this linker change appropriate? Does it need to change or revert? Does Wine
need to change? Thanks for any comments.
