A quick test of the concept is at
http://martin.st/temp/clang-forward-slash.patch; this seems to be roughly
enough to get forward slashes for all paths in the linker command at least.
Does this look like what you have in mind?
For a plain "clang -v test.c", this takes care of everything except the
temporary object file. It doesn't do anything for the compile command though.
This should be roughly the minimal amount needed for this particular case of
libtool, but then again makes the -v output wildly inconsistent.
Changing the path separator earlier would kinda require changing the preferred
path separator throughout all callsites to any path api, or change the path
utils to allow overriding the global default somehow.
