Hello,


Thank you for all the work on Cygwin! I've been using it to spin up an environment to build the OCaml compiler / toolchain, and it was working great.


However, today, all our CI builds mysteriously started failing - at first, I suspected it was a problem with AppVeyor, but I also failures with VSTS. We use an NPM package (`esy-bash`) to spin up a Cygwin environment, and then use that to build the OCaml toolchain.


The error message we started receiving today is:

OCAML_FLEXLINK="../boot/ocamlrun ../flexdll/flexlink.exe" ../byterun/ocamlrun ../ocamlc -g -nostdlib -I ../utils -I ../parsing -I ../stdlib -I ../compilerlibs -strict-sequence -safe-string -strict-formats -w +a-4-9-41-42-44-45-48 -warn-error A -custom ocamlcommon.cma -o ocamltest.exe run_win32.o run_stubs.o ocamltest_config.cmo testlib.cmo run_command.cmo filetype.cmo filecompare.cmo backends.cmo variables.cmo environments.cmo builtin_variables.cmo builtin_modifiers.cmo actions.cmo builtin_actions.cmo tests.cmo builtin_tests.cmo tsl_ast.cmo tsl_parser.cmo tsl_lexer.cmo tsl_semantics.cmo options.cmo main.cmo
x86_64-w64-mingw32-gcc: error: ../stdlib\libcamlrun.a: No such file or directory


The complete build log is here:

https://gist.github.com/bryphe/58603ab752ecd988f78ee383fa9c9e78


After some investigation, I was able to isolate the issue - environments with the 2.10.0-1 version of Cygwin built successfully, whereas newer environments with the 2.11.0-1 version exhibit this failure. The remaining packages are in parity - importantly, all the mingw packages we install are at the same version.


Results of cygcheck -c on both environments:

- Working environment: https://gist.github.com/bryphe/b11f72f60d9d7c04a8e709e6a8eb20ff

- Failing environment: https://gist.github.com/bryphe/7cf4e6216030781eb273ac45d36590cd


I'll continue to look around for a more minimal repro, but I suspect there may be other manifestations of it. It looks like there were a few path-related patches that came in to 2.11.0-1, so perhaps this scenario was impacted.


In the meantime - is there a way we can pin the cygwin package to the 2.10.0-1 version, to unblock our builds?


Thank you!

Bryan
