2022-06-29	Adapt to LLVM 15 trunk libc++ dropping std::unary_/binary_function	Stephan Bergmann
	...for C++17 and beyond with <https://github.com/llvm/llvm-project/commit/681cde7dd8b5613dbafc9ca54e0288477f946be3> "[libc++] Complete the implementation of N4190". (Unless explicitly opted-in with _LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION. This is similar to the MSVC standard library needing _HAS_AUTO_PTR_ETC=1 to enable those zombie functions for quite some time now. Only libstdc++ still supports them unconditionally.) Most uses of those zombie functions across LibreOffice itself and the bundled external/* are indirectly within Boost include files. And many (but not all) of those Boost include files only use those zombie functions conditionally, based on BOOST_NO_CXX98_FUNCTION_BASE. For the (Dinkumware-derived) MSVC standard library, workdir/UnpackedTarball/boost/boost/config/stdlib/dinkumware.hpp already defined BOOST_NO_CXX98_FUNCTION_BASE. So add a patch to define that also in workdir/UnpackedTarball/boost/boost/config/stdlib/libcpp.hpp (for all of C++11 and beyond, even if those functions were still available as deprecated in C++11 and C++14, but which shouldn't make a difference with our C++17 baseline anyway; only make sure that things still work if those Boost include files ever get used by code built with gb_CXX03FLAGS). (Patching our bundled external/boost of course doesn't help when building with such a new libc++ and --with-system-boost against an unpatched Boost, but lets consider that "not my problem". Also, one could always use a sledgehammer like passing CPPFLAGS=-D_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION into gbuild in such a case.) Then there are two places that include boost/multi_array.hpp, which indirectly includes workdir/UnpackedTarball/boost/boost/functional.hpp, which still uses those zombie functions for non-MSVC builds (at least in the bundled Boost 1.79.0). Lets do a targeted _LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION in those cases. (Alternatively, we could patch workdir/UnpackedTarball/boost/boost/functional.hpp. Also, I decided to make loplugin:reservedid support the new suppression mechanism, rather than extending its existing ignorelist even further.) And then there is external/clucene using those zombie functions even outside of a Boost include file, so extend the existing hack there that was already needed for MSVC. (And adapt the accompanying comment: For one, we are unconditionally "in C++17 mode" by now. And for another, the exact places where external/clucene uses those functions have apparently changed over time.)

2022-05-01	improve support for using libc++ on Linux and for libc++ debug mode	Luboš Luňák
	It seems to run slightly faster in --enable-dbgutil mode and also builds a bit faster (at least with Clang). But libc++ on Mac isn't built with debug mode support.

2019-10-14	add PCHs for more external libs	Luboš Luňák
	I think this is all external libs where it makes sense for them to have their own PCH and be worth it. Maybe some smaller externals can also use the common system PCH, but unfortunately many externals use all kinds of defines that affect system headers, which is a problem for the common system PCH.

2019-05-24	disable warnings in external libs	Luboš Luňák
	As in, really disable, so that they do not even show. This moreover avoids tons of D9025 warnings from MSVC about overriding -W4 with -w.

2019-04-25	Cut down on -pthread/-lpthread proliferation	Stephan Bergmann
	Building against libstdc++ effectively always requires -pthread anyway (as various standard C++ headers require it, see the comment added to solenv/gbuild/platform/unxgcc.mk), so many explicit uses of -pthread/-lpthread can be removed. Doing a (partial) test build on Linux with Clang -stdlib=libc++ suggests that libc++ indeed doesn't need -pthread as libstdc++ does. The remaining uses of -pthread/-lpthread are mostly in configure.ac for the various BSDs (which somebody else might want to clean up now), and related to external projects. I tried to be careful to remove -pthread/-lpthread from makefiles only when C++ object files are involved (so -pthread will now be included on the link command line by default).
