I'm encountering the same build failure as seen in from 2014. Though I'm opening a new issue as I'm sure there have been a lot of changes in the 7 years since, and apparently this bug was "Fixed in CVS" (@zorry). I'm not sure what change it was that had meant to fix it.

Note: I'm using the default USE flags for the cross compiler installation through crossdev
Comment 4 Tee KOBAYASHI 2021-12-01 01:09:19 UTC
I see "-fstack-protector-strong -D_FORTIFY_SOURCE=2" in your CFLAGS. It would be troublesome if cross-x86_64-w64-mingw32_ucrt/mingw64-runtime were built with these flags.
Comment 5 James Beddek 2021-12-01 01:26:28 UTC
Ah that's a duh on my part as I use the Clang compiler on my system, and Clang doesn't have sane semi-hardening defaults.

Now crossdev works a treat after switching mingw64-runtime to use a gcc env. Thanks for helping me fix this :)
