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