1/ remove boost regex code from 3rdparty/boost. Only the cmake stuff remains.
2/ remove traces of BOOST_LIB since there is no need anymore to
compile boost stuff.
3/ remove traces of boost regexp in config/lyxinclude.m4 and INSTALL
4/ require gcc 4.9 as minimal version in autoconf.
Unfortunately, the net gain is only 10% of included boost size (now 21M).

optimization of LyX. The compile may be much quicker with some
compilers, but LyX will run more slowly.
- o --disable-std-regex forces the compiler to use boost::regex. The
- default is to use std::regex for known good C++ libraries, but the
- test is not robust for clang. --enable-std-regex will force the
- use of std::regex.
-
o --enable-debug will add debug information to your binary. This
requires a lot more disk space, but is a must if you want to try
to debug problems in LyX. There is no run-time penalty.
o --enable-stdlib-debug adds some debug code in the standard
library; this slows down the code, but has been helpful in the
past to find bugs. Note that this is in general incompatible with
- the system boost library (which is used when
- --without-included-boost is specified). You may have to use
+ the system hunspell library (as of version 1.5). You may have to use
--disable-stdlib-debug when linking development versions against
- your system's boost library.
- The same problem applies to hunspell (as of hunspell 1.5). So either
- compile --with-included-hunspell or --disable-stdlib-debug when
- linking development versions against your system's hunspell library.
