[boost] Regex++ vs. g++ 2.91.66 (egcs-1.1.2)

For compatibility with some third-party software, I am forced to use g++ 2.91.66
on a Linux x86 platform.  If it is possible, I would like to use some of the
Boost libraries, as I do on my other platforms.  For the moment, I am interested
in the Regex++ library and in the scoped_ptr and scoped_array classes.

I have looked at the gcc.hpp header, which seems to support this version, but
building Regex++ was a catastrophe.  Additionally defining
BOOST_NO_STD_ALLOCATOR via a compile flag helped somewhat.

Then I figured out how to use configure to generate a user.hpp header.  That
resulted in these macros:

#define BOOST_MSVC6_MEMBER_TEMPLATES
#define BOOST_HAS_UNISTD_H
#define BOOST_HAS_STDINT_H
#define BOOST_HAS_SLIST
#define BOOST_HAS_SGI_TYPE_TRAITS
#define BOOST_HAS_SCHED_YIELD
#define BOOST_HAS_PTHREADS
#define BOOST_HAS_PTHREAD_MUTEXATTR_SETTYPE
#define BOOST_HAS_NL_TYPES_H
#define BOOST_HAS_NANOSLEEP
#define BOOST_HAS_LONG_LONG
#define BOOST_HAS_HASH
#define BOOST_HAS_GETTIMEOFDAY
#define BOOST_NO_USING_TEMPLATE
#define BOOST_NO_SWPRINTF
#define BOOST_NO_STD_WSTRING
#define BOOST_NO_STD_USE_FACET
#define BOOST_NO_STD_MESSAGES
#define BOOST_NO_STD_LOCALE
#define BOOST_NO_STD_ITERATOR
#define BOOST_NO_STD_ALLOCATOR
#define BOOST_NO_STRINGSTREAM
#define BOOST_NO_OPERATORS_IN_NAMESPACE
#define BOOST_NO_LIMITS_COMPILE_TIME_CONSTANTS
#define BOOST_NO_LIMITS

The build still fails at this point:

g++  -o generic/boost_regex/cregex.o -c -O2 -I../../../ -march=i686 -mieee-fp
-DBOOST_USER_CONFIG="<boost/config/egcs-1.1.2-config.hpp>" ../src/cregex.cpp
In file included from ../../../boost/regex.hpp:1530,
                 from ../src/cregex.cpp:27:
../../../boost/regex/detail/instances.hpp:108: syntax error before `<'
../../../boost/regex/detail/instances.hpp:135: confused by earlier errors,
bailing out

Is this hopeless?

If there is no way to use Regex++ with this ancient compiler, is it possible
that scoped_ptr and scoped_array might work?
