[boost] problem with WCHAR_MIN using gcc-4.1.1 on hpux11.11

Hi,

On HP-UX 11.11, there is a weird definition of WCHAR_MIN:

$ grep WCHAR_MIN /usr/include/*.h
/usr/include/wchar.h:#             define WCHAR_MIN  (wchar_t)0

When using gcc-4.1.1 on this platform, each time WCHAR_MIN is tested by
preprocessor-directive against zero, g++ spits:

gcc-C++-action ../../../bin/boost/libs/regex/build/libboost_regex.a/gcc/debug/c_regex_traits.o
In file included from ../src/c_regex_traits.cpp:29:
<snip>/boost_1_34_0rc/boost/regex/v4/regex_traits_defaults.hpp:87:94: error: missing binary operator before token "0"

This appears in
 boost/regex/v4/perl_matcher.hpp: line 53
and
 boost/regex/v4/regex_traits_defaults.hpp: line 87

Both of them are hidden for aCC with "#if !defined(__HP_aCC)",
so maybe they should also be hidden for gcc on hpux ?

This problem does not appear with gcc-3.4.5 because of this:

gcc-3.4.5 (don't exactly know until which version) did not define
_INCLUDE__STDC_A1_SOURCE as builtin, which enables that definition of
WCHAR_MIN in /usr/include/wchar.h

Initially I had this with 1.33.0, but it is the same for rc-1.34.0.

Thanks,
  haubi
