Sure, it is a lot of work and the current solution is only a start.
(for the time beeing you could replace "const_cast<char *>" with "mem.strdup")
"Pritty sure" is nice but having as much as possible automatic
detections is more important to me in the long run.

Trying to clean up the frontend for 64bit proved surpisingly hard.
64bit builds with gcc and icc show different behaviours.
Seemingly simple test cases like
http://dstress.kuehne.cn/run/l/large_id_01_D.d and
http://dstress.kuehne.cn/compile/template_class_08.d
fail for 64bit but pass for 32bit builds. etc.
