fanquake · fanquake · commit 05da2460db89 · 2024-04-07T14:06:27.000+01:00
The libs in this dir are the following:
```bash
ls /gnu/store/2vnbkrdin4rrf7ygnr80mlcglin4qqa4-gcc-toolchain-12.3.0-static/lib/lib
libanl.a           libc.a             libdl.a         libm.a
libBrokenLocale.a  libcrypt.a         libg.a          libmcheck.a
libpthread.a       librt.a
libresolv.a        libutil.a
```

These do not need to be propogated into the Windows build environment.
