## Windows-specific stuff

# Windows resource compiler support. libtool knows what to do with .rc
# files, but Automake (<= 1.11 at least) doesn't know.
#
# We want the resource file only in shared liblzma. To avoid linking it into
# static liblzma, we overwrite the static object file with an object file
# compiled from empty input. Note that GNU-specific features are OK here,
# because on Windows we are compiled with the GNU toolchain.
#
# The typedef in empty.c will prevent an empty translation unit, which is
# not allowed by the C standard. It results in a warning with
# -Wempty-translation-unit with Clang or -pedantic for GCC.
