30dnl `patsubst' here deletes the newline which "echo" prints. We can't use
31dnl "echo -n" since -n is not portable (see autoconf manual "Limitations of
32dnl Builtins"), in particular on solaris it results in a literal "-n" in
33dnl the output.

180dnl Added the following configure option in January 2008 following
181dnl investigation of problems with "64" system and library calls on
182dnl Darwin (MacOS X). The libguile code (_scm.h) assumes that if a
183dnl system has stat64, it will have all the other 64 APIs too; but on
184dnl Darwin, stat64 is there but other APIs are missing.
185dnl
186dnl It also appears, from the Darwin docs, that most system call APIs
187dnl there (i.e. the traditional ones _without_ "64" in their names) have
188dnl been 64-bit-capable for a long time now, so it isn't necessary to
189dnl use "64" versions anyway. For example, Darwin's off_t is 64-bit.
190dnl
191dnl A similar problem has been reported for HP-UX:
192dnl http://www.nabble.com/Building-guile-1.8.2-on-hpux-td13106681.html
193dnl
194dnl Therefore, and also because a Guile without LARGEFILE64 support is
195dnl better than no Guile at all, we provide this option to suppress
196dnl trying to use "64" calls.
197dnl
198dnl It may be that for some 64-bit function on Darwin/HP-UX we do need
199dnl to use a "64" call, and hence that by using --without-64-calls we're
200dnl missing out on that. If so, someone can work on that in the future.
201dnl For now, --without-64-calls allows Guile to build on OSs where it
202dnl wasn't building before.
