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