-### Picking the right LFS support flags for mod_perl, by Joe Orton ###
-#
-# on Unix systems where by default off_t is a "long", a 32-bit integer,
-# there are two different ways to get "large file" support, i.e. the
-# ability to manipulate files bigger than 2Gb:
-#
-# 1) you compile using -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64.  This
-# makes sys/types.h expose off_t as a "long long", a 64-bit integer, and
-# changes the size of a few other types too.  The C library headers
-# automatically arrange to expose a correct implementation of functions
-# like lseek() which take off_t parameters.
-#
-# 2) you compile using -D_LARGEFILE64_SOURCE, and use what is called the
-# "transitional" interface.  This means that the system headers expose a
-# new type, "off64_t", which is a long long, but the size of off_t is not
-# changed.   A bunch of new functions like lseek64() are exposed by the C 
-# library headers, which take off64_t parameters in place of off_t.
-#
-# Perl built with -Duselargefiles uses approach (1).
-#
-# APR HEAD uses (2) by default. APR 0.9 does not by default use either
-# approach, but random users can take a httpd-2.0.49 tarball, and do:
-#
-#   export CPPFLAGS="-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64"
-#   ./configure
-#
-# to build a copy of apr/httpd which uses approach (1), though this
-# isn't really a supported configuration.
-#
-# The problem that mod_perl has to work around is when you take a
-# package built with approach (1), i.e. Perl, and any package which was
-# *not* built with (1), i.e. APR, and want to interface between
-# them. [1]
-#
-# So what you want to know is whether APR was built using approach (1)
-# or not.  APR_HAS_LARGE_FILES in HEAD just tells you whether APR was
-# built using approach (2) or not, which isn't useful in solving this
-# problem.
-#
-# [1]: In some cases, it may be OK to interface between packages which
-# use (1) and packages which use (2).  APR HEAD is currently not such a
-# case, since the size of apr_ino_t is still changing when
-# _FILE_OFFSET_BITS is defined.
-#
-# If you want to see how this matters, get some httpd function to do at
-# the very beginning of main():
-#
-#   printf("sizeof(request_rec) = %lu, sizeof(apr_finfo_t) = %ul",
-#          sizeof(request_rec), sizeof(apr_finfo_t));
-#
-# and then put the same printf in mod_perl somewhere, and see the
-# differences. This is why it is a really terribly silly idea to ever
-# use approach (1) in anything other than an entirely self-contained
-# application.
-#
-# there is no conflict if both libraries either have or don't have
-# large files support enabled
