[kde-solaris] Bug 55818 impacts compiling kdelibs on Solaris 9

[Misty Stanley-Jones]

I don't know about previous versions of Solaris, but on Solaris 9,
alloca() is provided by alloca.h, not stdlib.h.  Therefore,
kdelibs/kio/kio/kzip.cpp needs to #include <alloca.h>.  I have submitted a
bug but wanted to give a heads-up to anyone who can fix this before
another KDE release is made.

Thanks,
Misty
