When you talk about config files, what do you mean?

a) user-config.jam or
b) gcc.jam

If you mean b) then I have to tell you: This is not a config file. Using 
the name config file is likely misleading. This file is part of the 
Boost.Build program.

If you mean a) then there is no need to speak about "force" because the 
intended use of config files is to be edited by users.

I do not understand this sentence:

Did you modify the file
a) because you know you need to compile with gnu compiler, but it was 
not being called, or
b) the gnu compiler is being called although you need to call aCC ?

In a previous post you told:

So I guess you tried to modify gcc.jam in an attempt to use aCC instead 
of gcc, yes?

Have you already seen this?
http://boost.org/boost-build2/doc/html/bbv2/advanced/configuration.html
http://boost.org/boost-build2/doc/html/bbv2/reference/tools.html

You might also be able to specify aCC here. But I am not sure if this 
works. You will need to try.

Sorry this not generally possible. Compare: if you have a Makefile and 
just say make, you will get what is the default. You will need to 
request certain targets if you want them. And yes the default might be 
platform dependant. Changing this would require contacting every lib 
maintainer to ask for a change of default settings. They might or might 
not have a reason for not default building a specific variant.

You still did not tell me if bjam gcc link=shared worked for you.

What do you think, I am feeling like ? ;-)

My basic question (since I have no experience with HP/UX) is: Is the 
compiler/linker toolchain already supported / tested with Boost.Build?
Are you the first one trying this?

If it is untested there might be two cases:

1) You (or someone else) need to add a complete fresh toolset 
description into boost.build.

2) Your toolchain is sufficiently compatible with gcc, i.e. just 
different name of compiler and linker: You could be able to configure 
this by giving the name of the compiler and options to the linker by 
means of your user-config.jam only.

Hmm, the only HP specific compiler I can see in the docs is
"HP C++ Compiler for Tru64 Unix"
http://h30097.www3.hp.com/cplus/?jumpid=reg_R1002_USEN

I guess this is not the one you are searching for...
