15 # available via anonymous FTP at tsx-11.mit.edu in
16 # /pub/linux/docs/linux-standards/fsstnd.
19 # but it doesn't seem sensible to put the binary in /usr and all the
20 # rest of the support stuff (lib, man pages) into /usr/local.
21 # However, allow a command line override, e.g. Configure -Dprefix=/foo/bar
26 # Perl expects BSD style signal handling.

29 # The following functions are gcc built-ins, but the Configure test
30 # may fail because it doesn't supply a proper prototype.
34 # Configure may fail to find lstat() since it's a static/inline
35 # function in <sys/stat.h>.
47 # Are we using ELF? Thanks to Kenneth Albanowski <kjahds@kjahds.com>
