I know. The problem is that AFAICS there is no way to use global variables
with existing AC_TRY_LINK macro. It might be possible with  more recent
AC_LINK_IFELSE macro (I haven't tested yet), but for some reason KDE
doesn't use any _IFELSE macros. I have to find out that reason at first -
just historic or these don't exist in supported autoconf version?

So, for now if this little patch solves the problem with Solaris, I will
commit this little fix and will leave further investigation into my TODO
list.
