But that will hurt performance on GNU/Linux and most other POSIXish hosts, as it will cause them to issue lseek system calls and whatnot that they don't need. Instead, wouldn't it be better to change gnulib/lib/stdio-impl.h so that it groks the musl FILE object? Naturally, this would inspect musl's "internals", but that'd be no different from all those other libraries that stdio-impl.h supports.
