MSVC's `link.exe` automatically finds `__cdecl` C functions (which are decorated with a leading underscore by the compiler) when they are mentioned in a `.def` file without the leading underscore. This is an [under-documented feature][1] of MSVC's `link.exe`. C++Builder's `ilink32.exe` doesn't do this, and thus needs the name-translation in the `.def` file. Then `implib.exe` needs to be told to re-add it. (The Clang-based `bcc32c.exe` doesn't implement the [`-vu` or `-u-`][2] options to skip adding the leading underscore to `__cdecl` C function names, so this is the only way to have things work with non-underscored export names in the DLLs.)
