robert f3c329d265 Do not try to work around ``poor (un)sign extension code'' 
creation by GCC-2.6.3.  Casting pointers to unsigned char
to volatile pointers to unsigned char seemed to produce
better results on the ia32 architecture with old versions
of GCC.
The current FreeBSD system compiler GCC-3.2.1 emits
better sign extension code for non-volatile variables:

volatile char c;
int i = c;

is compiled to:
...
movb	-1(%ebp), %al
movbsl	%al, %eax
movl	%eax, -8(%ebp)
...

char c;
int i = c;

is compiled to:
...
movbsl	-1(%ebp), %eax
movl	%eax, -8(%ebp)
...

The same holds for zero-extension of dereferenced pointers
to volatile unsigned char.
When compiled on alpha or sparc64, the code produced for the
two examples above does not differ.
