[Emacs-diffs] master 8ca2bd1 3/4: In CANNOT_DUMP builds, don't prepare for unexec. |

branch: master
commit 8ca2bd1ce7eebaf3b995786d9f9f61907ebbb060
Author: Ken Raeburn <address@hidden>
Commit: Ken Raeburn <address@hidden>
In CANNOT_DUMP builds, don't prepare for unexec.
Having a command-line argument of "dump" or "bootstrap" would trigger
behavior like not installing signal handlers. In CANNOT_DUMP modes,
we should get signal handlers installed regardless of whatever funny
file names we decide to edit.
src/emacs.c (main) [CANNOT_DUMP]: Don't enable the "dumping"
alterations to initialization that prepares the process for unexec.
