We noticed that, when called from genreflex, gccxml tries to call the compiler used to build it, which is on AFS.
This fails when the machine we are using to build does not have AFS.
After some investigations, I found that the problem is that genreflex does not pass the argument to "--gccxmlopt" to gccxml when calling it with --print.
The attached patch fixes the problem and extends the known compiler names to include "lcg-g++-*", which is the compiler name (wrapper) we use in LHCb (and that is used on the distcc cluster).
Can you add it to the next release, please?
