make fails on cygwin of the cvs source at 2009-12-24

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

Hello

I have tried to build the cvs source  at 2009-12-24.
The 'make' procedures failed on cygwin-1.5 and cygwin-1.7  

The snapshot of the error on cygwin-1.7

Making all in docs
make[2]: Entering directory `/cygdrive/d/usr/Tatsu/cyghome-1.7/gnuplotcvs/gnuplot/docs'
Makefile:73: *** Recursive variable `CC' references itself (eventually).  Stop.
make[2]: Leaving directory `/cygdrive/d/usr/Tatsu/cyghome-1.7/gnuplotcvs/gnuplot/docs'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/cygdrive/d/usr/Tatsu/cyghome-1.7/gnuplotcvs/gnuplot'
make: *** [all] Error 2


On cygwin1.5, the same error occurred.

Perhaps the above are side effect of following change.
2009-12-24  Robert Schwebel <r.s...@pe...>

	* configure.in docs/Makefile.in:
	When cross compiling gnuplot, build the documentation generation tools
	in docs/ with CC_FOR_BUILD (host compiler), not with the cross compiler.

Regards

Tatsuro
