Problems:
There was some debugging mechanism hacked into the astyle lib sources,
which added 'ASIgnore' & 'AS/Ignore' markers. Without this support,
generated sources contain these markers unconditionally and thus fail
the compilation:
projectmanagers/qmake/parser/qmakeast.h:13:1: error: expected unqualified-id <U+0001>!ASIgnore"!! ^
With the update to Astyle 1.24, this debugging mechanism got disabled.
(I don't really know what it's for...)
