you are building a Cygwin dll, that requires the Cygwin1.dll
but probably do you not intend it and need a standalone one that
requires only the MS system dll's.

install the Mingw crosscompiler x86_64-w64-mingw32-gcc.exe
that is in the package

$ cygcheck -f /usr/bin/x86_64-w64-mingw32-gcc.exe
mingw64-x86_64-gcc-core-7.4.0-1

and compile as
x86_64-w64-mingw32-gcc.exe -Wall dll.c -shared -fPIC -o dll.dll

Marco
