#3345 closed Patches (fixed)
Support for gettimeofday() in high_resolution_timer.

Description
On certain platforms, such as OS X (Darwin) util::high_resolution_timer ultimately defaults to using std::clock(). On this platform, and probably many others gettimeofday() is a reasonable, nominally microsecond precision, alternative.
Attached is a version which will make use of gettimeofday() if there are no alternatives and the existence of gettimeofday() is guaranteed by the macro BOOST_HAS_GETTIMEOFDAY.

I have just noticed there are some subtle problems with this. I will review them and upload a new version.

Thanks! I committed a patched version anyway (I was faster than you :-P). But I'll update it as soon as you found a fix for the problems.

Fixed update of the high_precision_timer - differences of unsigned integers are now explicitly mangaged.
A patched version of high_resolution_timer.hpp that includes support for gettimeofday() if it exists in preference to boost::timer().
