First substantive commit: the entire Sprinter C compiler tree on top of
the bare README+gitignore initial commit.
What's in here:
bin/sprinter-cc — driver script invoking SDCC + linker + mkexe
libc/ — Sprinter-specific libc layer over ESTEX/BIOS
(conio, gfx, io, mem, stdio + headers)
runtime/ — crt0 variants (default/small/banked/minimal)
+ heap + bank trampolines
toolchain/ — mkexe (SprintEXE packer, C + tests)
examples/ — 30 demo programs (gfx, file I/O, env, time, …)
lib/Makefile — builds the libc archive (sprinter.lib)
docs/ — converted Sprinter manuals + asm reference samples
third_party/ — solid-c reference compiler dump + sdcc setup script
release_docs/ — packaging / release notes
gitignore overhaul:
• Drop dangerous blanket patterns: *.asm (would hide docs/samples/*.asm)
and *.exe (case-insensitive match was hiding third_party/solid-c/*.EXE
on macOS APFS). Replaced with examples/*/*.{asm,exe,…} and lib/*.lib.
• Restore tracking of toolchain/mkexe/tests/{one,big}.bin — those are
INPUT fixtures, not build outputs.
• Collapse the duplicated SDCC/C/Sdcc sections into one section per
concern (build outputs / vendored / OS-junk).
• Add .sprinter-cc-*/, build/ (catches lib/build/ too), .claude/.

* fcntl.h — open / creat for Sprinter ESTEX.
|
|
*
|
|
* POSIX-style flag bits. The low two bits select access mode (matches
|
|
* POSIX numbering — RDONLY=0, WRONLY=1, RDWR=2 — and is translated to
|
|
* the ESTEX OPEN $11 convention inside open()).
|
|
*
|
|
* The other flags map onto ESTEX calls like this:
|
|
* O_CREAT + O_EXCL → $0B (CREATE_NEW, fails if exists)
|
|
* O_CREAT + O_TRUNC → $0A (CREATE, truncates existing)
|
|
* O_CREAT alone → try $11 (OPEN); on ENOENT fall back to $0A
|
|
* no O_CREAT → $11 (OPEN, fails if missing)
|
|
* O_APPEND → after open, $15 lseek(0, SEEK_END)
