Notes: v3 -> v4: - iatgas.h - LLVM(Clang), ARM, ARM64 support - Use __ASM_NAME macro - Don't fail test on MSVC - Don't end asm macros with "\n\t"
v4 -> v5: - iatgas.h - mark idata sections as RO - loader.c - test for forward export itself
v5 -> v6: - loader.c - Fix compilation warning in format string
v6 -> v7: - forward4.c - fix building without MinGW
v7 -> v8: - Also do GetProcAddress for forwarded ordinal exports - forward[1-3].c - Call DisableThreadLibraryCalls in DllMain - forward4.c: removed - iatgas.h: removed - sforward.c: new file - loader.c - test static forwarded import using shlwapi -> userenv forward
v8 -> v9: - Test with iprop (documented as an ole32 forwarder in MSDN [1])
