The problems the comments in the build systems refer to seem to have been
fixed for years. [1] says the checks in libstdc++ have been improved, and
all supported FreeBSD versions enable wchar_t support unconditionally in
libstdc++. Additionally, this needlessly impacts FreeBSD when libc++ is used
instead of libstdc++.

When we export the file to latex, we use the redefinition_ variable to check whether we should output newcommand or renewcommand. This variable was set by the MathMacroTemplate::metrics() function, and this caused problem when the export is running in a different thread as the GUI.
In general, the metrics() functions should not change the Buffer; we have updateBuffer/updateMacros for that purpose.
Not all accessors did update the data previously. Therefore it could happen
that document export from the command line would output \newcommand, and from
GUI it would output \renewcommand for the same macro, simply because in the
GUI case the data was updated as a side effect of the GUI thread reading some
other member.
I also removed the mutable flag for requires_, since this member is always
set on construction and does not need any lazy update.
The bug was introduced with commit [47f7d447/lyxgit], where the unnecessary trailing bracket in CJK environments was suppresed, but not the preceding bracket (which is only output if CJK is a secondary language).
This is the result of the discussion on the list "2.1.0 Blocker". Thanks to
all contributors!
The main idea is to use thread-local storage for all static variables.
This solution does not need any mutex. For more details, see the comment in
unicode.h.
It is no longer needed, and it had a comment that it needed review...
Now anybody who tries to make a copy again is forced to think about it,
instead of trying and using possibly wrong semantics by accident.
dvipdfmx emits a lot of warnings and Koji suggests ps2pdf.
Thanks to Koji for the advice.
Note that on Debian, I installed the following packages
to be able to compile with ps2pdf:
fonts-takao-mincho
fonts-ipafont-nonfree-jisx0208
fonts-ipaexfont-mincho
These workarounds are no longer necessary because of unicodesymbols
and further they break compilation with XeTeX as well as pdfTeX
with TeX input encoding set to ascii or utf8.
Thanks to Günter Milde for the fix.
