Re: Release plans: Version 4.4.4 and beyond

[Tatsuro M. <tma...@ya...>]

Hello

I have confirmed that 
Print NaN gives 0.0 for gnuplot 4.4.3 binary.

As written by Ethan, in the CVS source, the NaN issue is corrected here.
2010-10-10  Tatsuro Matsuoka  <tma...@ya...>

	* src/stdfn.c (not_a_number): Bit-pattern definition of NaN for MINGW

I also find the above log in the ChangeLog in gnuplot 4.4.3. I checked the source of 4.4.3.
The modification is also attached to the 4.4.3 source.
I do not find the reason why this modification is not effective for 4.4.3 binary.

Regards

Tatsuro
