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