Hi Dan,

I finally took a look at your spec file.  I have made extensive patches.
Here are some issues addressed:

1.  use standard macros  %{name} not %{Name} %{version} not %{Version} 
    %{post} not %{Post} etc.

2.  use the macro version of ALL commands.  some systems especially non
    linux ones have many versions of these commands with different
    command line arguments,e.g., %{__find} not find

3.  all spec files need changelogs IMNSHO

4.  the temp directory for rpm builds should be %{_tmppath} not /tmp or
    /var/tmp or /whatever

5.  use %{_includedir},%{_libdir}, etc for path names.  don't hardcode
    paths.

6.  pass CXX=%{__CC} into makefiles since you do not know which compiler is
    default.  Let the rpm macro file specify.  Makefiles need to accept
    this standard overide.

7.  On the description, consider line wrapping some of the entries. (I
    didn't patch this)

8.  Using g++ to link shared libraries with 2.95.2 only seems to work if
    you have a shared libstdc++ installed.  Since g++ linkage is so
    broken now, why bother with shared libraries?  That way built boost
    apps will still work across versions.

9.  in the patches in the rpm, don't assume linux ness, protect the
    linux specific changes with ifdefs...

There are a few non-rpm gotchas...  random_device has an #ifdef linux
check that is either too big or too small in scope.  None of the code in
it looks linux specific. (this probably isn't your problem).  I have
patched that as well.  I am still trying to get stuff to build clean 
on Solaris with GCC 2.95.2 in the RPM.  When I do, I'll send the
patch(es).

Hi,
I finally figured out why the regex++ shared library was crashing when
throwing an exception.  Somehow the shared library wasn't getting
created correctly by using ld to link it.  When using ld with c++ code,
some additional libraries need to be specified on the command line.  The
easy fix is to simply call g++ to link the files.  g++ then calls ld
with the appropriate commands.
So in this version of the RPM, I now use g++ to create the shared
library, and the regression test program runs flawlessly.
