X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=c3de50d70f8296f2b24316472bda4a053dd69e37;p=bamtools.git

Modified Utilities::FileExists() so it doesnt rely on sys/stat.h.  While this header is de facto provided and supported on *most* systems, it really is not standard C/C++, so cant be trusted to be fully portable.
