OK, I see the problem now.  So this means people who use GCC 2.95 will
have to use the previous version of dxe3gen.  In that case, I think
I'm okay with documenting this and ignoring the problem with GCC 2.95.

Sure, but we are already talking about someone who does something very
non-standard.  I just prefer that we leave those hypothetical people a
way of keeping their setups, whatever they are, and I think supporting
DJDIR and DXE_LD_LIBRARY_PATH for adding -L options to the command
line cannot do any harm to people who use the standard directories,
right?
