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