not that i know of, but this would definitely be useful ...

there are the platform directories (osx, windows, linux),
which should be used for this sort of stuff;
e.g. Process/Main could implement a method that is
overridden in a platform specific file:

+ Main {
    platform { ^\linux }
}

for Pathname we could follow a similar approach:

+ PathName {
    platformPathSeparator { ^$/ }
}

the handling of paths inside sclang could also be unified;
tcl for example converts all paths to unix conventions and
only converts them back when used externally. that way paths
can be split, concatenated etc. at will in the language.

i guess special care must be taken for windows X: style
drive ids.

good question ...
