"make distclean" failed for me today... after cleaning lots of stuff, it started trying to *build* something:
... make[1]: Leaving directory `/home/dank/wine-git/tools' config.status: creating tools/widl/Makefile make[1]: Entering directory `/home/dank/wine-git/tools/widl' ../../tools/makedep -C. -S../.. -T../.. client.c expr.c hash.c header.c proxy.c server.c typegen.c typelib.c typetree.c utils.c widl.c write_msft.c parser.y parser.l make[1]: ../../tools/makedep: Command not found make[1]: *** [depend] Error 127 make[1]: Leaving directory `/home/dank/wine-git/tools/widl' make: *** [tools/widl/Makefile] Error 2
Alexandre changed the build system today a bit, I wonder if that did it.
