X-Git-Tag: v0.22.1~17
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c3e3868fbf419792365d169037162c9cc4ba8743;p=thirdparty%2Fgettext.git

libgettextpo: Fix compilation error on Android.

* gettext-tools/libgettextpo/gettext-po.c: Include error.h second.
(orig_error, orig_error_at_line): New variables.
(error, error_at_line): Undefine afterwards.
(po_file_read_v2, po_file_write, po_error_logger, po_message_check_format): Use
these variables instead of the error, error_at_line symbols.
