* Unbreak doscmd after the sigset_t change:marcel1999-09-291-8/+8
| | | | | | | | | | | | doscmd heavily depends on struct sigcontext which luckily is mostly passed between functions as usion regcontext_t. By redefining union regcontext_t in terms of mcontext_t almost all bases are covered. It also seems to me that doscmd was in a transitional state. The redundant definitions made it difficult to get a clear overview and could easily cause oversight. To make sure my changes were ok, I went as far as to complete the transition. It was not exactly necessary, but I expect to have to come back here some more ("whistle" if I'm wrong :-).
