This doesn't work for me. If I do it like this all I get is this:
: bjam msvc-7.1 -q
...found 120 targets...

I.e. no compilation takes place at all, even though I did modify some
sources.

I think it does. It is great that is shows me the line in Jamroot.

What I meant was, can I have requirements on aliases? For example, something
like this:

# helper for platform-dependent ghal classes #########################
alias ghal_alias : ;
alias ghal_alias : [ glob GFL/GHAL/winnt_GHAL/*.cpp ] : <toolset>msvc ;
alias ghal_alias : [ glob GFL/GHAL/cygwin_GHAL/*.cpp ] : <toolset>gcc ;

# ghal alias
alias ghal
    : GFL/GHAL/tcpip.cpp
      ghal_alias

### requirements
    : <toolset>msvc:<name>WS2_32.lib
    ;

Use this in lib GFL target. The difference was that I could specify system
libraries
in my aliases instead of where I use the aliases (the lib GFL target).

By the way:
