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