/* This is a gross hack to get borken 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
thing 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 maximal number of character used for the conversion is
MB_CURLEN.
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. */
