# LuaTeX unconditionally builds the `luasocket` module: https://github.com/TeX-Live/texlive-source/blob/tags/texlive-2023.0/texk/web2c/Makefile.am#L292
# `luasocket` depends on various macros that require additional feature test macros. For example `gethostbyaddr()` requires `_GNU_SOURCE` or similar:
# https://github.com/TeX-Live/texlive-source/blob/tags/texlive-2023.0/texk/web2c/luatexdir/luasocket/src/usocket.c#L381
# The `configure.ac` for `web2c` (which also configures LuaTeX) should therefore contain something like `AC_USE_SYSTEM_EXTENSIONS`:
# https://www.gnu.org/software/autoconf/manual/autoconf-2.67/html_node/Posix-Variants.html
# However, it doesn't. The build still works with musl because some of its headers indirectly include `features.h` that defaults to `_BSD_SOURCE`, which is enough:
# https://git.musl-libc.org/cgit/musl/tree/include/features.h?h=v1.2.4#n15
# Cosmopolitan doesn't include `features.h` indirectly, so we have to define a sufficiently powerful macro (`_GNU_SOURCE`) right here.
# Also, the default `socket_waitfd()` implementation in `luasocket` includes a non-standard `sys/poll.h` header, which doesn't contain `struct pollfd` in Cosmopolitan:
# https://github.com/TeX-Live/texlive-source/blob/tags/texlive-2023.0/texk/web2c/luatexdir/luasocket/src/usocket.c#L19
# By defining `SOCKET_SELECT`, we fall back to a simple `socket_waitfd()` implementation that uses `select()` instead, which is perfectly fine for LuaTeX.

# -Wl,--allow-multiple-definition is required because busytex links several
# web2c engines (pdftex, xetex, luahbtex) into ONE executable that dispatches by
# argv[0]. The engines were generated independently and each emits its own copy
# of the same web2c symbols, so the link sees these duplicates (TL2026 sources):
#   `zisbitset`     — function, pdftex0.c vs xetex0.c
#   `outputcanend`  — .bss, pdftex-pdftexextra.o vs xetex-xetexextra.o
#   `savearitherror`— .bss, pdftex-pdftexextra.o vs xetex-xetexextra.o
# The definitions are equivalent web2c-generated globals, so taking the first
# (xetex's) is safe; the per-engine code paths never mix at runtime. A targeted
# fix would require patching/renaming generated web2c output across engines,
# which is not worth it. The flag stays until busytex stops single-binary linking.

	#  2. Strip the `!!` prefixes (TEXMFDIST/SYSCONFIG/SYSVAR/LOCAL). In kpathsea
	#     `!!` means "consult the ls-R database ONLY, never scan the directory".
	#     The packaged WASM VFS has no ls-R index, so leaving `!!` would make
	#     kpathsea find nothing; removing it lets kpathsea scan the VFS directly.
	#     Trade-off: directory scanning instead of an index lookup, acceptable for
	#     the small basic tree. Verify a compile still resolves packages/fonts.
