Backport fix for Bug#5723 from trunk.

parents 68ae6cda 184765cc
2010-11-04 Chong Yidong <cyd@stupidchicken.com>
* process.c (Fmake_network_process): Don't apply Bug#5173 fix for
Windows.
2010-11-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
* process.c (Fmake_network_process): Don't call turn_on_atimers around
`connect' (Bug#5723).
2010-11-04 Helmut Eller <eller.helmut@gmail.com>
* process.c (Fmake_network_process): Call `select' for interrupted
`connect' rather than creating new socket (Bug#5173).
2010-11-04 Kenichi Handa <handa@m17n.org>
* font.c (font_delete_unmatched): Check Vface_ignored_fonts.
