FWIW I cannot reproduce this here using MinGW 4.8.1. I am using 
config/mingw/Makefile to build. How do you build gnuplot?

I can reproduce the problem with VS2012, though. The reason is that the 
stupid _snprintf() (note the underscore) apparently sets errno if the 
buffer size is insufficient. This then triggers the above message. I'll 
prepare a fix for MSVC.

Could you try building with "-D__USE_MINGW_ANSI_STDIO"? That should 
should ensure that MinGW is using an ANSI compliant replacement of the 
snprintf function.
