My operating system is Windows x64
When I try to make ACE using Cygwin I get the following compilation error:

Steps I have done before trying to make:
1- I installed Cygwin64 using the installer and I installed the gcc-g++, gcc-core, make, perl and binutils packages.
2- I ran the cygserver-config script and it finished successfully.
3- I downloaded ACE from https://download.dre.vanderbilt.edu/, I chose the "Full" ACE.zip (7.0.0) from the Micro releases
4- I created the config.h file with #include "ace/config-cygwin32.h" in it and placed it in ACE_wrappers/ace/
5- I created the platform_macros.GNU with "include $(ACE_ROOT)/include/makeinclude/platform_cygwin32.GNU" in it and placed it in ACE_wrappers/include/makeinclude/
6- I opened the Cygwin64 shell and did this: export PATH=/cygdrive/c/cygwin64/bin:$PATH export ACE_ROOT=/cygdrive/c/resources/ACE_wrappers
7- I did "cd $ACE_ROOT/ace" then I "make".
For the gcc version (from Cygwin shell gcc -v):
Using built-in specs.

The cygwin64 port isn't actively maintained so you need to update the ace/config-win32.h for this. You need to try which defines should be added to that file, when you have done that and it works, contribute your changes upstream at https://github.com/DOCGroup/ACE_TAO
The issues section at https://github.com/DOCGroup/ACE_TAO is a better place for any ACE questions.
