Unicode error for gcc-11 commencement

Unicode error for gcc-11 commencement

[Greg Hogan]

Hi,

I would like to use both gcc-toolchain (for compiling) and
clang-toolchain (for the tools) in the same profile, which as
previously discussed requires the gcc version to match that used to
build clang, llvm, etc. So to use a newer gcc-toolchain I need to
upgrade the default gcc version.

When I attempt to upgrade the default gcc version from gcc-10 to
gcc-11 (or gcc-12) I see what looks to be an issue handling the
unicode filename of test files first added to gcc-11. The default gcc
is compiled as part of the bootstrap process which for x86-64 is guile
2.0.

In the guile 2.0 release notes [1] I see a familiar name as well as a
reference to Unicode support, so I am puzzled why this build is
failing. Any help is appreciated. Thanks!

The following is my patch, followed by the error message.

Greg
