a bunch of warnings

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Hello,

I'm sending a bunch of compiler warnings for gnuplot from two
different compilers. The first batch comes from Sparc Solaris, the
second one from clang on Mac OS X 10.7 (most warnings are recent, in
particular those about plot2d; the last three are older).
