Bootstrap failure w/3.2 trunk on sparc-solaris2.7 in insn-attrtab.c

[Kaveh R. Ghazi]

There's a new bootstrap failure on the 3.2 trunk for
sparc-sun-solaris2.7 when using cc for stage1.  I get this:

 > cc -DIN_GCC -g -DHAVE_CONFIG_H -I. -I. -I../../egcc-CVS20020501/gcc
 >   -I../../egcc-CVS20020501/gcc/. -I../../egcc-CVS20020501/gcc/config
 >   -I../../egcc-CVS20020501/gcc/../include -c insn-attrtab.c -o
 >   insn-attrtab.o
 > "insn-attrtab.c", line 11546: syntax error before or at: }
 > "insn-attrtab.c", line 11546: warning: syntax error:  empty declaration
 > cc: acomp failed for insn-attrtab.c
 > make[2]: *** [insn-attrtab.o] Error 2

The relevant declaration in insn-attrtab.c:11546 is:

 > const struct function_unit_desc function_units[] = {
 > };

GCC also warns about this not being valid:

 > insn-attrtab.c:11546: warning: ISO C forbids empty initializer braces

So any chip/platform for which this struct is empty will choke when
using an ISO C compliant compiler.

I'm pretty sure it started happening around the time of the dfa-branch
merge.  My guess is that you either need to avoid emitting the struct
if its empty or insert a dummy value if that's too problematic.
