CVS commit: src/sys/sys

Module Name:    src

Modified Files:
        src/sys/sys: cdefs.h

Log Message:
While visibility "protected" is nominaly supported by gcc 4.0 and 4.1
it does not actually work - the compiler does not emmit ".protected"
asm statements for used references to protected symbols, which then
causes the linker to fail and/or produce unloadable libraries.
This recently happened to port vax by the locale changes.

Backporting a fix (ASM_OUTPUT_EXTERNAL in gcc target config) is not
feasible.

So: define __dso_protected only starting with gcc 4.2.
