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