13 # If you wish to use something other than 'gcc' for your compiler,
14 # you should specify it on the Configure command line. To use
15 # gcc-elf, for exmample, type
16 # ./Configure -Dcc=gcc-elf
18 # perl goes into the /usr tree. See the Filesystem Standard
19 # available via anonymous FTP at tsx-11.mit.edu in
20 # /pub/linux/docs/linux-standards/fsstnd.
23 # but it doesn't seem sensible to put the binary in /usr and all the
24 # rest of the support stuff (lib, man pages) into /usr/local.
25 # However, allow a command line override, e.g. Configure -Dprefix=/foo/bar
30 # Perl expects BSD style signal handling.
31 # gcc defines _G_HAVE_BOOL to 1, but doesn't actually supply bool.

34 # The following functions are gcc built-ins, but the Configure tests
35 # may fail because it doesn't supply a proper prototype.
39 # Configure may fail to find lstat() since it's a static/inline
40 # function in <sys/stat.h>.
