Bug Report: \y, \B, \<, \> do not work with _

[Servatius Brandt]

Hello,

The \y, \B, \<, \> patterns do not regard _ as
word-constituent (unlike \w and \W, which do).

Operating system: ReliantUNIX-Y 5.44 C2001 RM600 R10000
Version of gawk: 3.0.6
C-Compiler: Fujitsu Siemens Computers CDS++ V2.0C0004

Test program:

#!/usr/local/bin/gawk -f

BEGIN {
    print match("X _abc Y", /\<_abc/)              # bug
    print match("X _abc Y", /\y_abc/)         # bug
    print match("X abc_ Y", /abc_\>/)              # bug
    print match("X abc_ Y", /abc_\y/)         # bug
    print match("X abc_def Y", /abc_\Bdef/)   # bug

    print match("X a_c Y", /a\wc/)            # ok!
    print match("X a.c Y", /a\Wc/)            # ok!
    exit
}
