Rewrite .zip.o file linker This change takes an entirely new approach to the incremental linking of pkzip executables. The assets created by zipobj.com are now treated like debug data. After a .com.dbg is compiled, fixupobj.com should be run, so it can apply fixups to the offsets and move the zip directory to the end of the file. Since debug data doesn't get objcopy'd, a new tool has been introduced called zipcopy.com which should be run after objcopy whenever a .com file is created. This is all automated by the `cosmocc` toolchain which is rapidly becoming the new recommended approach. This change also introduces the new C23 checked arithmetic macros. 2023-06-10 16:15:19 +00:00			`#ifndef COSMOPOLITAN_LIBC_STDCKDINT_H_`

Clean up more code - Found some bugs in LLVM compiler-rt library - The useless LIBC_STUBS package is now deleted - Improve the overflow checking story even further - Get chibicc tests working in MODE=dbg mode again - The libc/isystem/ headers now have correctly named guards 2023-06-18 07:55:09 +00:00
