I have updated Cygwin_x86 and Cygwin_x86-64 today.
In building the gnuplot I have met the error of "multiple definition of `atan2l'".
/usr/lib/gcc/x86_64-pc-cygwin/5.3.0/libstdc++.dll.a(d005836.o):(.text+0x0): multiple definition of `atan2l'
/usr/lib/../lib/libm.a(t-d000195.o):fake:(.text+0x0): first defined here
collect2: error: ld returned 1 exit status
Makefile:777: recipe for target 'gnuplot.exe' failed
This did not occur yesterday.
Perhaps the latest change gcc-5.3.0 give this results.
At the moment a workaroud is :
LDFLAGS='-Wl,--allow-multiple-definition' \
at configure.
