- extended signature with calling convention mode switches for fastcall (gnu), default, cdecl, stdcall, arm (arm), arm (thumb), syscall
- made formatted call (dcV?{Call,Arg}F) interface use those calling convention mode signature specifications to begin with
- extended callf testcode with one standard and one vararg call to test those cc mode switches

Build with GCC Tool-Chain: One assembly front-end *.S source file for all supported architectures: Usage: gcc -c dyncall_call.S -o dyncall_call.o Advantages: - works fine with universal binary builds (fat binaries), e.g.: gcc -arch i386 -arch ppc -arch x86_64 -c dyncall_call.S -o dyncall_call.o Details: Simplified assembly file compilation via using a gigantic C Preprocessor switch include. source file "dyncall_call.S" selects the appropriate GAS/Apple assembly file "dyncall_call_<arch>_<asmtool>.[sS]". archs so far: arm32_thumb .s arm32_arm .s mips .s ppc32 .s x64 .s x86 .S [ uses C macros ] asmtools: gas - standard GNU assembler apple - apple's assembler (based on GNU but is significantly different in syntax) masm - Microsoft assembler x86 and x64 nasm - Netwide assembler for x86 and x64 NOTE: .S is used for preprocessing assembly files using gcc .s is used directly with as advantages: - one way to build the kernel: gcc -c dyncall_call.S -o dyncall_call.o - we can build now universal binaries
