Invalid Windows .exe PE file
When I try to build GCC 11 for MinGW (using MinGW-w64 8.0.0) configure fails
(on both 32-bit and 64-bit) when it's trying to test if it can run a compiled
.exe file.
When I replicate this command with:
`echo "int main () { return 0; }" |

conftest.exe -g -O2 -xc -`
it builds `conftest.exe`, but running it (fro MSYS2 bash shell) with
`conftest.exe` fails with error `bash: ./conftest.exe: cannot execute binary
file: Exec format error`, or when I run it from Windows or Command prompt it
pops up a message saying `This app can't run on your PC`.
The command `file conftest.exe` does return `conftest.exe: PE32+ executable
(console) x86-64, for MS Windows`.
I have attached this file.
