Subject: Switch from using RETSIGTYPE via autoconf to void.
X-Git-Tag: mmh-thesis-end~170
X-Git-Url: http://git.marmaro.de/?p=mmh;a=commitdiff_plain;h=fc71710f8695ea07d852284286b058ecb3955317

Switch from using RETSIGTYPE via autoconf to void.
POSIX says that's the type to use for a signal handler.

Pulled in from nmh. Thanks to Ken Hornstein.
(btw: `to pull in' describes my action better than `to merge'.)
