with this you can now do:

 ./autogen.sh --enable-debug="sw sc"

and your build will have debug version of the libraries sw and sc, but a
non-debug build elsewhere. This currently only works for libraries. It would be
also possible to extend that to excutables, but that would need explicit in the
enable-debug switch then:

 ./autogen.sh --enable-debug="Library/sw Library/sc Executable/mkunroll"

so I dont know if it is worth it.

The line hight for the dialog box was not high enough; changed it from 8
to 10.

Had an embarrassing thinko in the assembler generation for the iOS
simulator, had forgotten the $ for a literal number. While at it, make
also the simulator read-only code snippet data structures
position-independent. Some minor comment improvements. Bridge seems to
work now on simulator.

Compiles, but I obviously have no idea how it works yet.

Yes, eventually we should factor out common parts from the iOS and
MacOSX code.
