https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65581

undefined reference to `WinMain'
Product: gcc
Version: 5.0
Status: UNCONFIRMED
Severity: normal

Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: rainer@emrich-ebersheim.de
Runnning the testsuites I see a real lot of FAILs like the following.
Executing on host:

I don't know if this is a w64-mingw runtime issue or a gcc issue.
