#2 0.49.D001 build failure on Arch Linux

[SpepS]

Hi, I'm the maintainer of libexplain on Arch Linux ( AUR > https://aur.archlinux.org/packages.php?ID=52960 ),
unfortunately i cannot build latest release 0.49.D001:

libexplain/buffer/errno/lseek.c: In function 'holes_are_not_supported':
libexplain/buffer/errno/lseek.c:60:32: error: '_PC_MIN_HOLE_SIZE' undeclared (first use in this function)

probably an #if defined(_PC_MIN_HOLE_SIZE) should be added before calling
result = fpathconf(fildes, _PC_MIN_HOLE_SIZE); in libexplain/buffer/errno/lseek.c

linux 3.1.8 - glibc 2.15 - libcap 2.22 - attached is a full build log.

Thanks

configure + make

Fix for this problem is in 0.50, available now on web site.
