What could be the problem when make gets into a loop in sax, continuously compiling facreg.cxx?

finally had time for a look, the problem is this:

in my master workdir there is indeed no such file:

the latter has been added in 2009 according to git log.

looks like your gcc writes broken dependency makefiles, can you verify
that
/Users/tml/lo/ios/workdir/unxiosr.pro/Dep/CxxObject/sax/source/fastparser/facreg.d
indeed lists this non-existant file?

what gcc version do you use... oh, that's an unusual one :)
