+Subject: [PATCH] fcitx-gclient: Export fcitx_client_enable_ic,
+ fcitx_client_close_ic (#521)
+
+Git-commit: 4f49f71a8b2c0852d3dfcd990d0b8bb61b1974c8
+
+These functions are used from fcitx-fbterm.  Adding function
+prototypes to the installed header file seems to be the cleanest way
+to ensure that fcitx-fbterm does not rely on implicit function
+declarations (which are likely to result in errors with future
+compilers by default).
