Works as is on Solaris 7 and later... with a caveat:

3@hilfy:217 Z# ls -l /proc/12079/cwd
lr-x------   1 root     other           0 Aug 23 09:21 /proc/12079/cwd -> /
3@hilfy:218 Z# /usr/proc/bin/pwdx 12079
12079:	/home/allbery/bld/gnome-network/network-utilities/CVS

It's more like linux 2.0 cwd symlinks than linux 2.2 cwd symlinks; you need 
to actually follow it to find its target.  Or use /usr/proc/bin/pwdx as 
above (which works on all versions of Solaris from 2.4 (I think) on, so is 
maximally compatible).
