* sysdeps/gnu/errlist-compat.awk: Don't bail if Versions gives a count higher than ERR_MAX reports. Instead, emit a #define ERR_MAX. * sysdeps/gnu/Makefile ($(objpfx)errlist-compat.h): New target. (generated): Add errlist-compat.h. * sysdeps/gnu/errlist.awk: Make output #include <errlist-compat.h> to define ERR_MAX and use that for table size.
