Oops, forgot a few other ones:

Merging improvements to Tango.Math into Phobos:
* internal functions isPosZero(), isNegZero() removed in favour of the more 
generally useful isIdentical().
* asm versions of functions which were not implemented by DMD Windows:  scalb, 
lrint.
* added creal expi(real y) which is useful for simultaneous calculation of sin + 
cos.
