Inform 6.21 patch to veneer.c
-----------------------------

With an addendum from Jon Ripley, see below.

As reported by Michael Baum in his post to rec.arts.int-fiction on 1999/05/05,
the following patch by Andrew Plotkin/ Torbjörn Andersson cures two bugs
which affect Inform 6/21 on some platforms: 

a memory error when compiling game files

a bug affecting the debug switch.

Replace lines 246 through 252 with:

         if (n==1) {\
           #ifdef DEBUG;n=debug_flag & 1; debug_flag=debug_flag-n;#endif;\
           print \"[ ~\", (name) obj, \"~.\", (property) id, \"(\";\
     switch(y) { 1: print a; 2: print a,\",\",b; 3: print a,\",\",b,\",\",c;\
     4: print a,\",\",b,\",\",c,\",\",d;\
     5: print a,\",\",b,\",\",c,\",\",d,\",\",e;\
     6: print a,\",\",b,\",\",c,\",\",d,\",\",e,\",\",f; }\
           print \") ]^\";\
           #ifdef DEBUG;debug_flag = debug_flag + n;#endif;\
           }",

The memory error was caused by the lack of the comma found at the end
of the patch.

I have tested the patch under Sun Solaris, and it does appear to cure the
bugs.

Addendum from Jon Ripley mailto:jon@stryker.freeserve.co.uk :

There were two spurious linefeeds in the original release of this patch which prevented the C code from being compiled.  This has been fixed and veneer.c should now compile without problems on all platforms.
