8+3-filesystem support

[Dr. Torsten Rupp]

Dear Classpath members,

some time ago there was a discussion how to support systems with a 
filesystem which are limited to 8+3-filenames (e. g. DOS-filesystem). 
Not so long ago there were also some messages concerning this and the 
introduction of a constant like ON_WINDOWS or isWin32. Now I have a 
system on which I like to use Classpath code with a 8+3-filenames, but 
with "/" as a separator (thus the current implementation of File.java is 
again not suitable).

My request: If you make some modifications like ON_WINDOWS or isWin32 
for the filesystem code, please take into account that:

1) 8+3-filesystems are _not_ limited to Windows-systems. Thus it would 
be better to name it fileSystem8_3 or something like that.

2) To decide if a filesystem is limited to 8+3-naming it would imho be 
nicer not to check if the separator character is "\" (because this fail 
on some systems which uses a 8+3-filesystem, but the more convenient "/" 
as a separator). Instead some system property would imho be better.

Sincerely,

Torsten
