Boris, 

 

I don't believe I found any documentation,  just an empirical
observation that somewhere after gcc 3.3.x wchar is available but not
knowing when exactly, played safe with requiring gcc > 4.0.

 

Cheers // Martin

This is because this configuration bug does not affect boost test
results -- check out HP-UX_pa_risc_gcc and HP-UX_ia64_gcc at
<http://beta.boost.org/development/tests/trunk/developer/summary.html>

and nobody complained. Quite a few people use gcc on HP-UX, but,
apparently, they do not use wregex.

Thanks for tha patch. Is it documented somewhere that wide character
support in gcc is available starting with version 3? Just want to be
sure. I did some google'ing and could not find definitive answer.
 
Thanks again,
