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