Subject: * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
X-Git-Tag: AUTOCONF-2.59d~124
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5455100eda81a8eedbb137015b2e2955ea625a33;p=thirdparty%2Fautoconf.git

* lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
AS_MESSAGE_LOG_FD before reopening it onto the log file.
This works around a MinGW bug reported by Eric Paire.
Make sure that all writes to the log file append to it,
rather than possibly losing data.
* lib/autotest/general.m4 (AT_INIT): Likewise.
