Hi Dennis, yes, as you mentioned, there are number of differences in the GNU and Solaris environment and I think maintainer of the Solaris version cares about it and patches official sources (in case if it's needed) at its discretion. Check these patches. It's hard to maintain one git-tree for all systems and platforms (don't forget - some of them are proprietar). This is the reason why each UNIX and UNIX-like system has its maintainer (even each GNU/Linux distribution has its screen maintainer).
I tested screen on OpenIndiana few weeks ago. It was version 4.6.1, I think, and it works perfectly :) What is the best size for PATH_MAX on Solaris? Sorry, but I don't know. Some systems use 255, some of them 4096... We took 1024. As I said, each maintainer is free to change this value at its discretion.
