OK, thanks. But i do not see it in Index of /11.x/x86/release/src/toolchain/. should be here also? Why not use musl lib, which is specially designed for static linking in programs? We talk here about X64, so not too much size gain/constrains.
my undestanding is that musl is both libc + link loader. so open a wide world of other (small) programs in tcz collection.
