/* The Solaris 2.0 x86 linker botches alignment of code sections.
It tries to align to a 16 byte boundary by padding with 0x00000090
bytes. The linker pads it to 16 bytes with a single 0x90 byte, and
two 0x00000090 ints, which generates a segmentation violation when
executed. This macro forces the assembler to do the padding, since
