[Msys2-users] Problem with building msys->mingw cross-compiler

[Иван Т. <tr...@gm...>]

I was trying to build mingw-w64-cross-gcc according to PKGBUILD provided
(for gcc-9.3.0) when i have run into the following issue.
Compilation goes on until it is time for configuration of
x86_64-w64-mingw32/libgcc in build tree. It then fails to configure.

Here is relevant section of config.log:

What could be going on there?
