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