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