------- Additional Comments From jh junetz de  2005-12-08 23:41 -------
I'm still seeing this on Sparc/Solaris 8, KDE 3.5, gcc 4.0.2, patches applied, \
configure rebuilt. The problem seems to be that the madvise test in configure passes \
even though the function is not available in the form used in ksycoca.cpp.

The error is:

ksycoca.cpp: In member function 'bool KSycoca::openDatabase(bool)':
ksycoca.cpp:148: error: 'madvise' was not declared in this scope

The relevant lines from config.log:

configure:43591: checking for madvise
