[GRASS5] G57 compile errors in r.mapcalc

[Funkmeister]

Hello,

I have had problems building r.mapcalc, seems to be related to the 
y.tab.c target. I am not sure if this is related to G53 or G57? I am 
compiling on a Mac G5.

Output from make:
bison -y -b OBJ.powerpc-apple-darwin7.3.0/y -d mapcalc.y
bison: OBJ.powerpc-apple-darwin7.3.0/y.tab.c: No such file or directory
bison: fclose: Bad file descriptor
bison: fclose: Bad file descriptor
bison: fclose: Bad file descriptor
<snip>

The line: bison: fclose: Bad file descriptor would go on for thousands 
of lines, and then crash.

It appears that y.tab.c was to be placed into the OBJ dir, but the OBJ 
dir was not yet created. Also, it doesn't seem like y.tab.c should be 
place into the OBJ dir at all.

So I changed:

y.tab.c y.tab.h: mapcalc.y
         $(YACC) -b $(OBJDIR)/y -d mapcalc.y
         $(MKDIR) $(OBJDIR)
         $(CC) $(LDFLAGS) $(INC) $(XTRA_LDFLAGS) -o $(OBJDIR)/$*.o -c 
$*.c

to:

y.tab.c y.tab.h: mapcalc.y
         $(MKDIR) $(OBJDIR)
         $(YACC) -b y -d mapcalc.y
         $(CC) $(LDFLAGS) $(INC) $(XTRA_LDFLAGS) -o $(OBJDIR)/$*.o -c 
$*.c

And it works for me.
