Aw: Re: No subshell in Rational ClearCase environment

[elek76 arcor de]

Hi,

Thanks for your help and sorry for being so silent for this long, but I didn't have much time to investigate 
this problem...
Anyway, this morning I installed pt_chwon, checked /dev/pts, everything seemed to be OK but the subshell 
didn't start.
I found out that it's the grantpt(pty_master) call in src/subshell.c:1176 (v4.6.0) that fails. I simply 
commented it out just to try what happens.
And it works now :)

Cheers,

Elek
