Is there workaround to build it successfully on Cygwin?

Is there workaround way to build native Windows SF binary successfully on Cygwin with mingw-x86_64 packages completely installed?

$ make profile-build ARCH=x86-64-modern COMP=gcc extra=yes lto=yes
Config:
debug: 'no'
sanitize: 'no'
optimize: 'yes'
arch: 'x86_64'
bits: '64'
kernel: 'CYGWIN_NT-10.0'
os: 'Windows_NT'
prefetch: 'yes'
popcnt: 'yes'
sse: 'yes'
pext: 'no'

Flags:
CXX: g++
CXXFLAGS: -Wall -Wcast-qual -fno-exceptions -std=c++11  -pedantic -Wextra -Wshadow -m64 -DNDEBUG -O3 -DIS_64BIT -msse -msse3 -mpopcnt -DUSE_POPCNT -flto

make[2]: Leaving directory '/usr/src/Stockfish-master/src'
make[1]: Leaving directory '/usr/src/Stockfish-master/src'

Step 4/4. Deleting profile data ...
make ARCH=x86-64-modern COMP=gcc profileclean
make[1]: Entering directory '/usr/src/Stockfish-master/src'
make[1]: Leaving directory '/usr/src/Stockfish-master/src'

$
$ objdump stockfish.exe |grep -i '^\s*dll'
DllCharacteristics      00008000
        DLL Name: cygwin1.dll
        DLL Name: cygstdc++-6.dll
        DLL Name: KERNEL32.dll

Resulted in an executable engine file with cygwin1.dll linking, even though mingw64-x86_64xxxxx installations are all set.. Any idea?

This is the stockfish repository and you are trying to compile cfish. Please close this issue.

The same issue and result after updating correct source above

$ objdump stockfish.exe |grep -i '^\s*dll'
DllCharacteristics      00008000
        DLL Name: cygwin1.dll
        DLL Name: cygstdc++-6.dll

I recommend to use MSYS2 instead of Cygwin, you can follow the guide below. https://github.com/glinscott/fishtest/wiki/Building-stockfish-on-Windows

Cygwin always used own dll's... You should to use MINGW from MSYS2 or MINGW32/64-gcc with COMP=mingw (static build).
