Subject: build: Don't rename error{_at_line} to rpl_error{_at_line} on native Windows.
X-Git-Tag: v0.22~39
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4874d5b8498d5343ef5d29484654007fb4bde43a;p=thirdparty%2Fgettext.git

build: Don't rename error{_at_line} to rpl_error{_at_line} on native Windows.

* gettext-tools/configure.ac (GNULIB_REPLACE_ERROR): Define only on Cygwin and
Android.
* gettext-tools/woe32dll/gettextlib-exports.c: Don't assume that
GNULIB_DEFINED_ERROR implies GNULIB_REPLACE_ERROR.
