I don't see that this can ever have built on 32-bit FreeBSD (i386 in particular) because the code uses Sxword, which our elf32.h doesn't define. The Linux elf.h (which hanbles both sizes) does define a 64-bit Sxword. The patch throws in a using (typedef, but C++-style) that mimics the 64-bit integers used in the Linux headers; this 64-bit value doesn't match the size of Elf32_Dyn fields in either OS, but I'll take a warning over non-stop build failures any day.
