New Revision: 6928

Modified:
   trunk/gs/src/genarch.c
Log:
Remove the requirement for HAVE_LONG_LONG to be defined before generating
ARCH_LOG2_SIZEOF_LONG_LONG. Since this was added, we've begun requiring
both signed and unsigned 64 bit types. Almost all platforms with a 64 bit
int provide long long, so this defaulting to on is a better approach.

We make an exception for MSVC which we support and which does not provide
'long long'. The requirement for a 64 bit type is taken care of by a matching
platform-specific #ifdef section in stdint_.h.

To add support for other such platforms, add another platform option to this
#ifdef and a corresponding section to stdint_.h.

Bug 688805 for customer 613.
