It's complicated.  The upstream maintainer of gettext REALLY dislikes a 
mechanism used for symbol resolution by the GNU toolchain (gcc/ld) with 
DLLs on mingw and cygwin: "auto-import".  So, he arranges that gettext 
is always compiled with --disable-auto-import.

However, recent versions of g++'s runtime library, libstdc++, ITSELF, 
require auto-import when linking IIUC.  Hence, boom.

I'm not sure this is easily fixed.  IF I am correct, there are two 
options: (1) teach g++ how to build a libstdc++ DLL that exports symbols 
"properly" rather than requiring auto-import.  This depends on a new 
cygwin g++ compiler I think.  OR, (2) override the build procedure for 
gettext to ensure that --enable-auto-import is provided on every link 
command, AFTER the "default" gettext setting of --disable-auto-import.

IIRC, just setting LDFLAGS before configuring won't do it, because Bruno 
*deliberately* arranged things to make overriding his desired 
auto-import behavior difficult.
