--- Comment #6 from lh_mouse <lh_mouse at 126 dot com> --- (In reply to Jonathan Wakely from comment #4) > Please provide the missing information that https://gcc.gnu.org/bugs/ asks > for, so we know how you configured GCC. The following command shows how gcc has been configured: ``` E:\>i686-w64-mingw32-gcc -v Using built-in specs.
