What exactly are you trying to do? Are you trying to compile for 32-bit Cygwin (which is unsupported but should be possible, though I didn't test multilib sysroots)? Or are you trying to cross-compile to 32-bit MinGW (that should absolutely work)? One of the failed tests that needed investigation was mingw sysroot trying to use /usr when it shouldn't, maybe this is what's going on here? -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
