Replace CHECK_CXX_SOURCE_COMPILES() with TRY_COMPILE()
Discarding the link-stage mimics the behaviour used by automake.
Now the testsource is compiled regardless if hunspell
is external or not.
The compile test for 3rdparty hunspell is omitted,
because the macro check_cxx_source_compiles() tries also to link.
But at the time of the check, the required library is not there.
A function that returns a vector<string> will lead to a crash if the
main code and the library have not been compiled with the same
stdlib-debug state. See for example:
https://stackoverflow.com/questions/4764048/stl-and-release-debug-library-mess
This is fixed by introducing a new variable STDLIB_DEBUG that contains
the flags that trigger the debug mode (autoconf only for now).
This will allow to go forward with bug #10547.
With advent of qt5 glyphs on codepoints 10, 12, 13 can't be shown anymore.
In this patch we copy the glyph pairs to new codepoints:
dotsint: 19->41 (this one was already moved by Goerg, now moving to the same block)
oint: 11->43
oiint:13->45
I couldn't find fix where both qt4 & qt5 would show correct results,
so this patch fixes qt5 situation, but breaks qt4, which hopefully
won't be needed for master.
Testing and debuging is somewhat tricky, becuse qt sometimes prefer to
load global fonts in /usr/share while ignoring the local git tree.
To be continued in other fonts.

These file don't contain the \\origin tag. So the possibly included
files with relative path would not be found. The compilation to
the default pdf would then anyway fail.
* Implement list item overlay support (\item<arg>)
* Implement itemcommand support (e.g., \overprint<arg>)
* Fix general list argument placement
Part of: #11068
Implemented: Overlay and standard overlay arguments for commands
and environments.
Still missing:
* List item overlay
* itemcommand overlay (\overprint)
* overlay via LatexParam (e.g., Flex:ArticleMode)
Needs fixing:
* General list argument (\begin{itemize}[arg])
* nested content in a frame with no title (empty par)
