getgrouplist implementation compatible with kdelibs?

[Adriaan de Groot]

Does someone have an LGPL compatible implementation of getgrouplist()? I 
imagine one from glibc would do. Something that can be added to kdefakes, in 
any case, because Solaris doesn't have getgrouplist and the FreeBSD 
implementation I have handy is 4-clause BSD licensed (strange, I thought the 
4-clause had been removed by the UCB years ago).

Given such an implementation, I can make ./kio/kfile/kpropertiesdialog.cpp 
compile again on non-Linux, non-FreeBSD but still-UNIX platforms.
