Comment (by albatros at icemx.net):

 OK, this time I really did get xaos to compile, and it even seems to
 work... This required two changes to the source code:

 1) Moved the contents of src/include/formulas.h to src/include/fractal.h
 (in an intelligent way, the #defines to the beginning, the extern
 declarations to the end, plus change one or to #includes to reference
 fractal.h instead of formulas.h). This got rid of the errors about a
 struct declared for an unknown type in formulas.h.

 2) Changed a register from bx to cx in an assembler inline in
 src/engine/i386.c because the assembler complained about "PIC register bx
 clobbered" (which seems strange because I didn't see any PIC on the
 command line of the compiler, but I didn't bother to investigate further).
