Subject: Pathnames missing devices were using 'UNSPECIFIC rather than #F.
X-Git-Tag: 20090517-FFI~9488
X-Git-Url: https://birchwood-abbey.net/git?a=commitdiff_plain;h=445ddb660ab8fb04f2a0d2aa888fd0be434b0c27;p=mit-scheme.git

Pathnames missing devices were using 'UNSPECIFIC rather than #F.
'UNSPECIFIC means that the field is meaningless in the host file system.
#F means that it was not specified.
