stdfn.h: error: conflicting types for 'memcopy' and 'sys_errlist' on Cygwin build

Hello
This is probably an issue that is specific to the Cygwin.
At compiling src/boundary.c I have met errors.
../../gnuplot/src/stdfn.h:67:8: error: conflicting types for 'memcpy'
../../gnuplot/src/stdfn.h:171:14: error: conflicting types for 'sys_errlist'
Full output.
