regex back references not implemented ?

We are looking for doing some regular expression substitution with the
using the back references of the regex.
We are working with FS indexing, and we have a path like : 1998_08_17
   replace "(.+)_(.+)_(.+)" "/cgi-bin/toto?year=$1&month=$2&day=$3"
   $1, $2, and $3 are not substituted.

We use SunOs 2.5. 
Is it a problem with solaris regex implementation (C library?), any
patch known for it ?
Htdig seems to use posix 2 Gnu regex implementation, why swish doesn't ?
