major gawk bug

[Stanislav Ievlev]

Hello friends!

Why gawk uses setlocale(), but have a hardcoded table  (const char casetable[] )
for case-independent regexp matching?

This table is correct for latin1 charset only, but incorrect for others,
e.g. for KOI8-R (russian).

KOI8-R encoding is fully compatible with 7-bit ASCII (so gawk compiles well),
but has other symbols for codes greater then 128.

So gawk supports only latin1, but ignore cp1251,koi8-r,koi8-u, etc.

As I understand, it's not a problem to fill this table with locale
specific symbols at start.
