[B2-devel] [PATCH] Large file support

[Gwenole B. <gb...@di...>]

Hi,

Following feature request #496122, here is a patch:
<http://sourceforge.net/tracker/index.php?func=3Ddetail&aid=3D496122&group_=
id=3D2123&atid=3D352123>

OK to commit? Tested on IA-32 with a 3 GB hard disk file.

Note: I unconditionnaly define _USE_LARGEFILE_SUPPORT and
_FILE_OFFSET_BITS whatever the underlying OS is. This is a glibc
specificity, I believe.

For gcc3/Fortran, some people defined _XOPEN_SOURCE to 500 instead of
_USE_LARGEFILE_SOURCE. So is _XOPEN_SOURCE_EXTENDED for Irix 6.2 because
struct timeval would not be declared otherwise.
