--disable-stdlib-debug when linking development versions against
your system's boost library.
- o --enable-concept-checks adds some compile-time checks. There is no
- run-time penalty.
-
o --enable-monolithic-build[=boost,client,insets,mathed,core,tex2lyx,frontend-qt4]
that enables monolithic build of the given parts of the source
code. This should reduce the compilation time provided you have
[enable_stdlib_debug=no])]
