| // For example, msvcrt.lib embeds a linker directive like: |
| // /DEFAULTLIB:vcruntime.lib /DEFAULTLIB:ucrt.lib |
| // So that vcruntime.lib and ucrt.lib are included when the entry point |
| // in msvcrt.lib is used. Using /NODEFAULTLIB would mean having to |
| // manually add those two libraries and potentially further dependencies |
| // they bring in. |
