Please ignore my previous patch for this. _ecvt and _fcvt needed a lot
more work than I first realized. The existing code had at least the
following problems: added a decimal point to the output, used scientific
notation in the output, did not remove the leading '-' for negative
numbers, and got the decimal point offset wrong for numbers like 0.0003.
This patch fixes all that and very closely matches the behavior of ecvt
an fcvt in glibc and _ecvt and _fcvt in Visual Studio 2005. I have
dropped the changes to _gcvt. I will deal with that later.
I have another patch that I will submit shortly that simply implements
_ecvt and _fcvt in terms of ecvt_r and fcvt_r. I actually like that
patch better since it is much simpler and leverages glibc better. I am
submitting both patches because I am not sure why ecvt_r and fcvt_r were
not used in the first place. Maybe they are not portable enough or
something like that.
I'm not sure that this will be accepted. Portability is really
important. I think our float implementation might be wrong from what I
remember. You ought to add test cases.
