1999-12-13 Andreas Jaeger <aj@suse.de> * resolv/resolv.h: Remove K&R compatibility. * resolv/res_libc.c: Move definition of _res after res_init, res_init should use the threaded specific context. * resolv/Makefile (+cflags): Remove -Wno-comment since it's not needed anymore. * locale/langinfo.h: Add constants for wide character collation data. * locale/categories.def: Add appropriate entries for collate entries. * locale/C-collate.c: Add initializers for new entries. * locale/programs/ld-collate.c: Implement output of wide character tables. * locale/programs/ld-ctype.c (allocate_arrays): Change algorithm to compute wide character table size a bit: it now gives up a bit of total table size for fewer levels.

|
|
* to be the static default, we can't detect it and unexpected results
|
|
* will follow. Zero for any of these fields would make no sense,
|
|
* so one can safely assume that the applications were already getting
|
|
* unexpected results.
|
|
*
|
|
* _res.options is tricky since some apps were known to diddle the bits
|
|
* before res_init() was first called. We can't replicate that semantic
|
|
* with dynamic initialization (they may have turned bits off that are
|
|
* set in RES_DEFAULT). Our solution is to declare such applications
|
|
* "broken". They could fool us by setting RES_INIT but none do (yet).
