Trouble compiling expat

[Marc LeMaire]

Hello you all !
I've just installed a fresh version of Freebsd 4.9 stable, cvsupped the 
port, build and install a generic kernel and world. I've done 
mergemaster and everything is ok.

The problem arises when I try to compile Kde, Moz, LyX. Each of these 
programs crashes with the same message :

building for expat-1.95.7
-------------
lib/xmlparse.c:76:#error memmove does not exist on this platform, nor is 
a substitute available
***Error 1

How can I fix this problem (or install the appropriate substitute)? I 
contacted the port maintainer but I have no reply yet.

Regards

Marc
