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