[Boost-users] Problem 2 with Boost 1.31.0 Regex for tru64cxx65

Having persuaded everything to compile in the 1.31.0 Regex library, it 
runs into another problem in building the .a archive libraries:

tru64cxx65-Archive-action bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a
/bin/sh: /bin/ar: arg list too long

...failed tru64cxx65-Archive-action bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a...

The problem is due to the number of instantiations in the template 
repository and the lengths of their names.  There are 492 
instantiations, and many of them have 90-character file names, which 
looks like the compiler's maximum allowed.

I solved the problem in previous versions of boost by breaking up the 
build into separate steps.  This was the way I modified the make file:

AR:= ar -cq
IIDIR:= $(LIBDIR)/cxx_repository

$(DIRNAME)/lib$(LIBNAME).a : $(ALL_O)
        @echo "*** creating lib$(LIBNAME).a"
        rm -f $@
        $(AR) $@ $^
        @echo "*** adding template instantiations"
        $(AR) $@ $(IIDIR)/[_A-Z]*
        $(AR) $@ $(IIDIR)/[a-z]*

It builds the library from just the object files and then adds the 
instantiations in two steps.  (Apparently, adding all of them exceeded 
the same shell arg list limit.)

How can I do something equivalent with bjam to build the library?
