cvs-1.11.17-8.RHEL4

When the CVS history file gets bigger than 2GB, cvs checkouts and other
operations on the server fail with a "File size limit exceeded" error.

The fix (verified) is adding the following line to the .spec before the make:
CFLAGS="$CFLAGS -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE"; export CFLAGS

$ cat filler.c
#include <stdio.h>

main()
{
  FILE *fp;
  fp = fopen("/var/cvs/CVSROOT/history","a+");
  while (1) fprintf(fp,"A448ee4ee|marco|~/cvstest|testprj|1.1|hello.txt\n");
  fclose(fp);
}

$ mkdir /var/cvs
$ mkdir /var/cvs/testprj
$ export CVSROOT=/var/cvs
$ mkdir cvstest && cd cvstest
$ cvs init

$ echo "hello world" > testprj/hello.txt
