Compiling the following simple file makes suns as complain:
---------
foo()
{
    (void) bar(42);
}
---------

gcc -fpic -S -O2 (-O2 doesn't matter, the code just gets shorter)
produces the following illegal assembly code:
----
	.file	"foo.c"
	.version	"GNU C 2.2.2"
	.optim
gcc2_compiled.:
.text
	.align 4
.globl foo
foo:
	pushl %ebp
	movl %esp,%ebp
	pushl %ebx
	call .L2
.L2:
	popl %ebx
	addl $_GLOBAL_OFFSET_TABLE_+[.-.L2],%ebx
	pushl $42
	call bar@PLT				<= illegal character
	movl -4(%ebp),%ebx
	leave
	ret
---------
cc -pic -S -O produces the following code:
---------
	.file	"foo.c"
	.version	"sun386-1.0"
	.optim
.LL0:
        .data
	.text
	.globl	foo
foo:
	pushl	%ebp
	movl	%esp,%ebp
	pushl	%ebx
	call	.+5
	pop	%ebx
	add	$_globtb_offset,%ebx
	pushl	$42
	call	bar,%eax			<= this is ok
	popl	%ecx
/ASMQ
	movl	-4(%ebp),%ebx
/ASMEND0
	leave	
	ret	
/FUNCEND

        .data
