[cvsnt] Compile failure with 2.5.02 on Linux

[Torsten Martinsen]

I just tried to install 2.5.02.1914 on a Debian Linux (Sarge) box.
 
The compilation failed with
 
g++ -DHAVE_CONFIG_H -I. -I. -I.. -I.  -I../lib -I../cvsapi -I../diff
-I../xmlapi -I../cvsapi -I../cvsgui -I../zlib -I../expat -I../expat/lib
-I../libltdl   -DCVS_CONFIG_DIR=\"/etc/cvsnt\"
-DCVS_LIBRARY_DIR=\"/usr/local/lib/cvsnt\" -g -O2 -c -o subr.o `test -f
'subr.cpp' || echo './'`subr.cpp
subr.cpp:48:20: xtime.h: No such file or directory
