It then worked when I compiled regex library as static... building it as 
dynamic produces a dll which g++ is not able to link with (it doesn't 
find the regex functions).

The problem with /usr was actually due to the way msys handles that 
special directory (as I saw in the documentation).

Just for curiosity: do you use the msys shell or do you use the dos 
command prompt to perform the compilation of your programs with mingw?

Because now there seems to be a problem about the way msys shell handles 
command line arguments:

--title="My title"

is interpreted as

--title=My title

which is wrong
