Fix Windows 7 support (#19) This change pays off technical debt with the function -> DLL mappings in libc/nt/master.sh, which was originally defined based on binary analysis on Windows 10. It's now been updated so the kernel32/kernelbase/advapi32 imports should be exactly as they are written, on the MSDN documentation and that wouldn't have been easy without Geoff Chappell's work thank him https://www.geoffchappell.com/studies/windows/win32/index.htm 2020-12-28 21:47:19 +00:00			`.imp kernel32,__imp_ReadFileEx,ReadFileEx,0`
Make terminal ui binaries work well everywhere Here's some screenshots of an emulator tui program that was compiled on Linux, then scp'd it to Windows, Mac, and FreeBSD. https://justine.storage.googleapis.com/blinkenlights-cmdexe.png https://justine.storage.googleapis.com/blinkenlights-imac.png https://justine.storage.googleapis.com/blinkenlights-freebsd.png https://justine.storage.googleapis.com/blinkenlights-lisp.png How is this even possible that we have a nontrivial ui binary that just works on Mac, Windows, Linux, and BSD? Surely a first ever achievement. Fixed many bugs. Bootstrapped John McCarthy's metacircular evaluator on bare metal in half the size of Altair BASIC (about 2.5kb) and ran it in emulator for fun and profit. 2020-10-11 04:18:53 +00:00
