+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.
