But make it issuing a warning anyway. Posix neither clearly allows it nor does it clearly forbide it (it's only saying about "<tab>command", and there's never a definition saying the empty string were a valid command or not; at least, it's a very useless one). The warning will not bother those too much who're only caring for porting other software, while it will allow fixing bogus makefiles as well. When reading Posix, i don't think our ``make'' is very far away from a Posix-compliant make. The intention of Posix here is to define only a subset of required commands, while leaving all the usual extensions as implementation-specific. One thing that will be necessary is to default the CC variable to ``c89'' instead of ``cc''. Perhaps this should be done via some .ifdef coding and the pseudo-target ``.POSIX'' which is required for all Posix-compliant Makefiles. (Maybe `make' will require internal logic to transform the .POSIX into an internal macro.) `c89' itself is no big deal. A script as simple as #!/bin/sh exec cc -ansi $* should do it. Note that some vendor cc's might have more problems here since it appears that Posix requires the c89 to accept spaces after the -l, -L, and-I options as well (which gcc does). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
