[bug-grep] Re: grep

[flavio]

Ciao,

   I eventually decided to stick to 2.5.1a.

I tried to compile in both modes (i.e. with the included regex and
without) and all is fine, even if I've seen that the old Spencer test #55
has disappeared and the Bond test has been modified to cope with the libc
limitation.

Regards,

   Flavio Poletti.
