An earlier version just included the original -# by "reference", using GNU cpp's #include_next mechanism. -# This is currently not done, partly because #include_next is -# fragile (susceptible to version incompatibilities, and depends -# and GCC-specific features), and partly for performance reasons. -# -# AUTHORS -# Ron Guilmette (rfg@netcom.com) (original idea and code) -# Per Bothner (bothner@cygnus.com) (major re-write) - -dirname=`echo "$0" | sed 's,^[^/]*$,.,;s,//*[^/]*$,,'` -progname=`echo "$0" | sed 's,.*/,,'` -original_dir=`${PWDCMD-pwd}` -FIX_HEADER=${FIX_HEADER-$original_dir/fix-header} -DEFINES="-D__STDC__=0 -D__cplusplus ${FIXPROTO_DEFINES}" - -if mkdir -p . 2> /dev/null; then - # Great, mkdir accepts -p - mkinstalldirs="mkdir -p" -else - # We expect mkinstalldirs to be passed in the environment. - # If it is not, assume it is in the directory that contains this script. - mkinstalldirs=${mkinstalldirs-"/bin/sh $dirname/mkinstalldirs"} - if $mkinstalldirs . 2> /dev/null; then - : - else - # But, in case of failure, fallback to plain mkdir, and hope it works - mkinstalldirs=mkdir - fi -fi - -if [ `echo $1 | wc -w` = 0 ] ; then - echo $progname\: usage\: $progname target-dir \[ source-dir \.\.\. \] - exit 1 -fi - -std_files="ctype.h dirent.h errno.h curses.h fcntl.h grp.h locale.h math.h pwd.h setjmp.h signal.h stdio.h stdlib.h string.h sys/socket.h sys/stat.h sys/times.h sys/resource.h sys/utsname.h sys/wait.h tar.h termios.h time.h unistd.h utime.h" - -rel_target_dir=$1 -# All files in $src_dir_all (normally same as $rel_target_dir) are -# processed. -src_dir_all=$2 -# In $src_dir_std (normally same as /usr/include), only the -# "standard" ANSI/POSIX files listed in $std_files are processed. -src_dir_std=$3 - -case $rel_target_dir in - /* | [A-Za-z]:[\\/]*) - abs_target_dir=$rel_target_dir - ;; - *) - abs_target_dir=$original_dir/$rel_target_dir - ;; -esac - -# Determine whether this system has symbolic links. -if ln -s X $rel_target_dir/ShouldNotExist 2>/dev/null; then - rm -f $rel_target_dir/ShouldNotExist - LINKS=true -elif ln -s X /tmp/ShouldNotExist 2>/dev/null; then - rm -f /tmp/ShouldNotExist - LINKS=true -else - LINKS=false -fi - -if [ \! -d $abs_target_dir ] ; then - echo $progname\: creating directory $rel_target_dir - $mkinstalldirs $abs_target_dir -fi - -echo $progname\: populating \`$rel_target_dir\' - -include_path="" - -if [ `echo $* | wc -w` != 0 ] ; then - for rel_source_dir in $src_dir_all $src_dir_std; do - case $rel_source_dir in - /* | [A-Za-z]:[\\/]*) - abs_source_dir=$rel_source_dir - ;; - *) - abs_source_dir=$original_dir/$rel_source_dir - ;; - esac - include_path="$include_path -I$abs_source_dir" - done -fi - -done_dirs="" -subdirs_made="" -echo "" >fixproto.list - -for code in ALL STD ; do - - subdirs="." - - case $code in - ALL) - rel_source_dir=$src_dir_all - - dirs="." - levels=2 - while $LINKS && test -n "$dirs" -a $levels -gt 0 - do - levels=`expr $levels - 1` - newdirs= - for d in $dirs ; do - # Find all directories under $d, relative to $d, excluding $d itself. - # Assume directory names ending in CC or containing ++ are - # for C++, so skip those. - subdirs="$subdirs "`cd $rel_source_dir/$d; find . -type d -print | \ - sed -e '/^\.$/d' -e "s|^\./|${d}/|" -e 's|^\./||' \ - -e '/CC$/d' -e '/[+][+]/d'` - links= - links=`cd $rel_source_dir; find $d/. -type l -print | \ - sed -e "s|$d/./|$d/|" -e 's|^\./||'` - for link in $links --dummy-- ; do - test -d $rel_source_dir/$link/. && newdirs="$newdirs $link" - done - done - dirs="$newdirs" - subdirs="$subdirs $newdirs" - done - ;; - STD) - rel_source_dir=$src_dir_std - ;; - esac - - case $rel_source_dir in - /* | [A-Za-z]:[\\/]*) - abs_source_dir=$rel_source_dir - ;; - *) - abs_source_dir=$original_dir/$rel_source_dir - ;; - esac - - if [ \! -d $abs_source_dir ] ; then - echo $progname\: warning\: no such directory\: \`$rel_source_dir\' - continue - fi - - for rel_source_subdir in $subdirs; do - - abs_target_subdir=${abs_target_dir}/${rel_source_subdir} - if [ \! -d $abs_target_subdir ] ; then - if $mkinstalldirs $abs_target_subdir ; then - subdirs_made="$abs_target_subdir $subdirs_made" - fi - fi - # Append "/"; remove initial "./".
