Fails to build with clang-15 but builds ok with gcc-12.

Sigh, this plugin is problematic (previous fix was for gcc 13)

I wonder if I had managed to reproduce it? With llvm-17, this command passes:
AR="llvm-ar" AS="clang -c" LD="ld.lld" CXX="clang++" CC=clang LDFLAGS="-Wl,-O1 -Wl,--as-needed -fuse-ld=lld -rtlib=compiler-rt -unwindlib=libunwind -Wl,--as-needed " USE=litehtml ebuild claws-mail-4.1.1-r2.ebuild compile

This workaround unfortunately does not work for me. Tried on a musl-system though (with -unwindlib=llvm-libunwind) not on glibc.

Same for claws-mail-4.2.0.

Ok, checked on a glibc system. There it builds ok with clang.

My findings so far:

+litehtml glibc-gcc-system:
gcc build     ...   works ok
clang build   ...   works ok

+litehtml musl-clang-system:
gcc build     ...   works ok
clang build   ...   FAILS

So the issue seems a bit more musl-related than clang-related.
