[Aldor-l] byacc --> zacc

[Ralf Hemmecke]

As we all know the Aldor compiler requires byacc for proper compilation. 
'bison' does not work.

Unfortunately, the make process silently ignores the error coming from a 
broken build and later hangs itself trying to compile lang.as.

The following patch stops the build when that error occurs.

It is in aldor/tools/unix/Makefile.
The patch basically replaces ; by &&.

Could someone please apply that patch? (You should restart the svn 
server before...)

Thanks.

Ralf
