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