dnl Added the following configure option in January 2008 following
dnl investigation of problems with "64" system and library calls on
dnl Darwin (MacOS X). The libguile code (_scm.h) assumes that if a
dnl system has stat64, it will have all the other 64 APIs too; but on
dnl Darwin, stat64 is there but other APIs are missing.
dnl
dnl It also appears, from the Darwin docs, that most system call APIs
dnl there (i.e. the traditional ones _without_ "64" in their names) have
dnl been 64-bit-capable for a long time now, so it isn't necessary to
dnl use "64" versions anyway. For example, Darwin's off_t is 64-bit.
dnl
dnl A similar problem has been reported for HP-UX:
dnl http://www.nabble.com/Building-guile-1.8.2-on-hpux-td13106681.html
dnl
dnl Therefore, and also because a Guile without LARGEFILE64 support is
dnl better than no Guile at all, we provide this option to suppress
dnl trying to use "64" calls.
dnl
dnl It may be that for some 64-bit function on Darwin/HP-UX we do need
dnl to use a "64" call, and hence that by using --without-64-calls we're
dnl missing out on that. If so, someone can work on that in the future.
dnl For now, --without-64-calls allows Guile to build on OSs where it
dnl wasn't building before.
