To my knowledge only Visual C++ has the ability to perform linking through pragmas, the comment pragma works by leaving a linker comment in the object file (hence the name), meaning this only works with the Visual C++ linker, so while clang does support this pragma with clang-cl, for the use cases in the JDK it wouldn't matter. gcc does not have an equivalent pragma (or provide support for linking from inside source files at all, for that matter)

There isn't any difference between the 2 unless the library is tampered with by `-nodefaultlib`, but I can only find that specified in https://github.com/openjdk/jdk/blob/a033aa5a3d9c63d72d11af218b9896b037fbd8de/make/autoconf/flags-other.m4#L38 and https://github.com/openjdk/jdk/blob/392f35df4be1a9a8d7a67a25ae01230c7dd060ac/make/autoconf/lib-hsdis.m4#L45, neither of which have an effect on the libraries in this changeset
