Hi. In Cygwin x86_64, the build fails with a bunch of "narrowing conversion
from ‘int’ to ‘wchar_t’" errors:

There are also lots of warnings like:

fish-3.1b1-1.x86_64/src/fish-3.1b1/src/common.cpp:1307:34: warning:
comparison is always false due to limited range of data type

static_cast<wchar_t>(0x10FFFF);
                         ~~~~~~~~~^~~~~~~~~

and

At global scope:
cc1plus: warning: unrecognized command line option ‘-Wno-redundant-move’
