We stopped adding "Contributed by" or similar lines in sources in 2012 in favour of git logs and keeping the Contributors section of the glibc manual up to date. Removing these lines makes the license header a bit more consistent across files and also removes the possibility of error in attribution when license blocks or files are copied across since the contributed-by lines don't actually reflect reality in those cases. Move all "Contributed by" and similar lines (Written by, Test by, etc.) into a new file CONTRIBUTED-BY to retain record of these contributions. These contributors are also mentioned in manual/contrib.texi, so we just maintain this additional record as a courtesy to the earlier developers. The following scripts were used to filter a list of files to edit in place and to clean up the CONTRIBUTED-BY file respectively. These were not added to the glibc sources because they're not expected to be of any use in future given that this is a one time task: https://gist.github.com/siddhesh/b5ecac94eabfd72ed2916d6d8157e7dc https://gist.github.com/siddhesh/15ea1f5e435ace9774f485030695ee02 Reviewed-by: Carlos O'Donell <carlos@redhat.com>

/* This is a gross hack to get broken programs running.
|
|
|
|
ISO C provides no mean to find out how many bytes the wide
|
|
character representation really uses. But it defines MB_CUR_LEN to
|
|
return the information for the multi-byte character representation.
|
|
Many programmers don't know the difference between the two and
|
|
think this means the same. But assuming all characters have a size
|
|
of MB_CUR_LEN after they have been processed by `mbrtowc' is wrong.
|
|
Instead the maximum number of characters used for the conversion is
|
|
MB_CUR_LEN.
|
|
|
|
It is known that some Motif applications have this problem. To
|
|
cure this one has to make sure the glibc uses the function in this
|
|
file instead of the one in locale/mb_cur_max.c. This can either be
|
|
done by linking with this file or by using the LD_PRELOAD feature
|
|
of the dynamic linker. */
