Consider the following test program:

----------------------------------------
main ()
{
  printf ("hello world\n");
}
----------------------------------------

When compiled with the -a and -p options on a Sun 4/260 running
Sun OS 4.0, the following occurs:

----------------------------------------
gcc version 1.34
 /usr/public/lib/gnu/gcc-cpp -v -undef -D__GNUC__ -Dsparc -Dsun -Dunix
 -D__sparc__ -D__sun__ -D__unix__ test.c /tmp/cca28201.cpp 
GNU CPP version 1.34
 /usr/public/lib/gnu/gcc-cc1 /tmp/cca28201.cpp -quiet -dumpbase test.c
 -a -version -p -o /tmp/cca28201.s 
GNU C version 1.34 (sparc) compiled by GNU C version 1.33.9.
 as /tmp/cca28201.s -o test.o
as: "/tmp/cca28201.s", line 28: error: redefinition of symbol "LPB0"
----------------------------------------

Here's the asm:
