Comment (by evanmiller):

 Quick update here after some fooling around this afternoon. I found a
 "magic" compiler flag that let me restore the {{{static_assert}}}s in the
 code base that I had commented out earlier: {{{-mone-byte-bool}}}. The
 {{{bool}}} type is a 4-byte integer by default on Tiger/PPC, but a 1-byte
 char on Intel. This results in different layout and sizes when bools are
 packed into structs. But passing {{{-mone-byte-bool}}} to GCC on PPC
 results in an Intel-compatible bool size, and should fix some instances of
 highly optimized code. (Of course, as the
 [https://gcc.gnu.org/onlinedocs/gcc/Darwin-Options.html docs] note, it
 could also break ABI compatibility with external libraries that expose
 {{{bool}}}s.)

 Unfortunately the {{{js60}}} shell still isn't starting for me on Tiger,
 so nothing else to report for now.
