[Gm2] GM2 on Solaris/Sparc: Option -0 considered harmful

[John O Goyo]

Greetings:

There is something about "-0".

./xgm2 -O -Wnil -Wcase -Wbounds -Wreturn -g  -funbounded-by-reference 
-Wverbose-unbounded -Wpim -Wpedantic-param-names -Wextended-opaque 
-Wpedantic-cast -c -B./stage2/gm2 
-I../../../src/gcc-4.1.2/gcc/gm2/gm2-compiler 
-I../../../src/gcc-4.1.2/gcc/gm2/gm2-libs 
-I../../../src/gcc-4.1.2/gcc/gm2/gm2-libiberty 
../../../src/gcc-4.1.2/gcc/gm2/gm2-compiler/NameKey.mod -o 
gm2/gm2-compiler-paranoid/NameKey.o
Internal error: Segmentation Fault

Remove "-0" and it compiles without incident.  The same holds true for 
gm2/gm2-compiler/NameKey.mod,
gm2/gm2-compiler/SymbolTable.mod,
gm2/gm2-compiler/bnflex.mod,
gm2/gm2-compiler/M2SubExp.mod,
gm2/gm2-libs/FIO.mod,
gm2/gm2-libs/Environment.mod,
gm2/gm2-libs/DynamicStrings.mod, and others.  I stopped here.

Sincerely,
