The attached patch makes some progress; actually it simply moves to a later Debian patchset. third_party/pdfium now compiles with it, but the build fails later on with the attached error message. So I have not yet pushed the patch, since it does not solve the problem; or would it be okay to push partial progress? The problem looks precisely like the bug here: https://bugs.gentoo.org/786597 which is supposed to be fixed upstream a long time ago. But their patch https://786597.bugs.gentoo.org/attachment.cgi?id=732880 still applies... It is also in the Debian patches as fixes/clang-and-gcc11.patch. Something to try another day!
