Description
Hi,
Compiling xapian-core-0.7.1 on a current Debian testing system causes a compile-time error on the file `backends/quartz/btree.cc', because pread() is unknown. Consulting the man page of pread() on my system shows:
SYNOPSIS
#define _XOPEN_SOURCE 500 #include <unistd.h>
Adding the #define solves the problem.
I wonder why configure set HAVE_PREAD, but that's secondary.

Should be fixed in CVS, and so in 0.7.2 when it's released.

configure finds pread because it just checks if it can link to a function when supplying its own prototype.
