- Add generic-musl to WASI include path: Zig 0.14.0 moved features.h out of wasm-wasi-musl/ into generic-musl/, but wasm-wasi-musl/stdio.h still includes it, causing compilation failures. - Work around zig lld colon-link bug (ziglang/zig#23287): zig 0.14.0 lld does not handle -l:filename syntax. Resolve such flags to full paths in zig-wrapper by searching the -L directories. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

Zig 0.14.0 no longer auto-links against the C library for build-exe targets. cp.zig uses stdlib functions (copyFile, argsAlloc) that call macOS system APIs, requiring explicit -lc. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
Zig 0.14.0 dropped the implicit -D_GNU_SOURCE that 0.12.0 passed. Without it, glibc headers gate POSIX extensions (posix_openpt, grantpt, unlockpt, ptsname, ...) behind __USE_XOPEN_EXTENDED/__USE_XOPEN2KXSI, which are only enabled when _XOPEN_SOURCE>=500/600. This broke CGO stdlib compilation on Windows cross-compiling to Linux (internal/testpty). Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
Zig 0.14.0 locates the macOS SDK by running xcrun --show-sdk-path. Bazel sandboxes clear PATH via 'exec env -', making xcrun unfindable and causing zig build-exe to fail with undefined system symbols (abort, arc4random_buf, fcopyfile, etc.). Restore /usr/bin:/bin in PATH on macOS so xcrun can be found. Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>
