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