Multiple targets and make -j

[Martin Schröder]

Hi,
I'm trying to make the makefiles of teTeX work with make -j.
Unfortunately they contain rules where one program call generates
multiple targets, like

pdftexini.c pdftex0.c pdftex1.c pdftex2.c pdftex3.c pdftexcoerce.h pdftexd.h: 
pdftex.p $(web2c_texmf)
        $(web2c) pdftex

Here $(web2c) pdftex has to called only once and not 7 times.

Any ideas how to achive this?

Thanks in advance
        Martin
