[Bug java/18104] New: Incorrect CLASSPATH separator in libjava breaks bootstrap

[aaronavay62 at aaronwl dot com]

The libjava Makefiles are hardwired to use ':' as a CLASSPATH separator.  Gcj,
however, picks the separator based on system-specific configuration, and so
correctly chooses ';' on MinGW.  This will cause bootstrap in libjava to fail
when the incorrect CLASSPATH separator as used, as it sees all components of the
CLASSPATH as a single file, and so cannot find any files.

Would it make more sense for GCJ to accept ':' instead of/as well as ';' on
mingw? Perhaps with some logic to distinguish a drive-letter ':'? The Makefiles
are sure ugly now with all this CLASSPATH_SEPARATOR stuff :(

I agree with you with regards to the ugliness.

The entire situation is really too bad; the mutually incompatible path
separators used by Unix and Windows is definitely one of the top ten
compatibility problems in build systems.

GCJ definitely needs to accept ; on Windows, as whats what javac does.  I think
it would also be excellent if it accepted :, but I don't know the whole story
behind this.  In particular, I think there was some sort of code that could
handle nontrivial Windows path separator parsing, somewhere in GCC, but it was
removed, or something.  I really don't know enough about the issue to fix it myself.

Maybe there is some other way to fix this in the Makefiles, to make it so it
isn't so ugly?  Should a bug be opened for "CLASSPATH_SEPARATOR in Makefiles is
ugly"?
