+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
