Use libc from agbcc instead of standalone newlib\nYou must have AGBCC commit 80d029caec189587f8b9294b6c8a5a489b8f5f88 in order to compile pmd_red.gbalibc

-! C run time start off
-
-! This file supports:
-!
-! - both 32bit pointer and 64bit pointer environments (at compile time)
-! - an imposed stack bias (of 2047) (at run time)
-! - medium/low and medium/anywhere code models (at run time)
-
-! Initial stack setup:
-!
-!    bottom of stack (higher memory address)
-! 	...
-!	text of environment strings
-!	text of argument strings
-!	envp[envc] = 0 (4/8 bytes)
-!	...
-!	env[0] (4/8 bytes)
-!	argv[argc] = 0 (4/8 bytes)
-!	...
-!	argv[0] (4/8 bytes)
-!	argc (4/8 bytes)
-!	register save area (64 bits by 16 registers = 128 bytes)
-!	top of stack (%sp)
-
-! Stack Bias:
-!
-! It is the responsibility of the o/s to set this up.
-! We handle both a 0 and 2047 value for the stack bias.
-
-! Medium/Anywhere code model support:
-!
-! In this model %g4 points to the start of the data segment.
-! The text segment can go anywhere, but %g4 points to the *data* segment.
-! It is up to the compiler/linker to get this right.
-!
-! Since this model is statically linked the start of the data segment
-! is known at link time.  Eg:
-!
-!	sethi	%hh(data_start), %g1
-!	sethi	%lm(data_start), %g4
-!	or	%g1, %hm(data_start), %g1
-!	or	%g4, %lo(data_start), %g4
-!	sllx	%g1, 32, %g1
-!	or	%g4, %g1, %g4
-!
-! FIXME: For now we just assume 0.
-
-! FIXME: if %g1 contains a non-zero value, atexit() should be invoked
-! with this value.

-! We use %g4 even if the code model is Medium/Low (simplifies the code).
-
-	clr	%g4			! Medium/Anywhere base reg
-
-! If there is a stack bias in effect, account for it in %g5.  Then always
-! add %g5 to stack references below.  This way the code can be used with
-! or without an imposed bias.
