Re: Cannot complie internal.c of cvs source (2011-01-02) on Cygwin

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

Hello

Thank you for immediate response and treatment.

Build on the Cygwin with the cvs source dated 2011-01-03 was successful.
Fine!!

Cygwin
gnuplot> print time(0),time(0.),time(" %Y/%m/%d %H:%M:%02.6S")
347398005 347398005.468875 2011/01/03 19:26:45.468875

MinGW
gnuplot>  print time(0),time(0.),time(" %Y/%m/%d %H:%M:%02.6S")
347398047 347398047.453125 2011/01/03 19:27:27.453125

DJGPP 
gnuplot>  print time(0),time(0.),time(" %Y/%m/%d %H:%M:%02.6S")
347430489 347430489.76 2011/01/04 04:28:09.760000

Note that the result in DJGPP is different from those in Cygwin and MinGW.
Perhaps DJGPP uses JST (Japanese Standard Time, UTC+9) and Cygwin and MinGW use UTC.

I do not know which you would like to implement.

No problem. One of the purpose of my frequently build of the CVS source is to kill the bug as soon as
possible. Faster finding issue is better for debugging.
