Agreed. And in options-speak, "explicit relocs" means both -mexplicit-relocs
and -msplit-addresses. The associated gas warning was disabled in the
initial revision of sourceware binutils:
1.1 (rth 03-May-99): #if 0 /* GCC code motion plus incomplete dead code elimination
1.1 (rth 03-May-99): can leave a %hi without a %lo. */
1.1 (rth 03-May-99): if (pass == 1)
1.1 (rth 03-May-99): as_warn_where (l->fixp->fx_file, l->fixp->fx_line,
1.1 (rth 03-May-99): _("Unmatched %%hi reloc"));
1.1 (rth 03-May-99): #endif
so I think this problem has been seen with GCC 2 as well as 3 and 4.
