# HG changeset patch
# User Ian Jackson <Ian.Jackson@xxxxxxxxxxxxx>
# Date 1282062053 -3600
# Node ID e5a9221bdd3fec99bc4b01afe56ef639cc9be60a

tools/libxl: compile with -Wmissing-declarations
Since the recent build error caused by mismatch of symbol types due to
missing declarations, build libxl with -Wmissing-declarations.
The patch is mostly straightforward, a one liner in the makefile enables
the flag, a lot of functions in xl_cmdimpl.c needed to be made static
and libxl_paths.c needed to include libxl.h.
The one wart on the patch-set is that flex has a bug where it emits code
with missing declarations for yy(set|get)_column. This can be worked
around by providing the declarations ourselves regardless.
