Greetings,
Below you may find a trivial patch for the cygstart program (a part of
the cygutils package) for your review:

#ifdef __CYGWIN__
/* Convert file path from POSIX to Windows, unless it looks like a URL */
if (!strstr (aPath, "://") && strncmp (aPath, "mailto:", 7) != 0)
It makes the double slash after the scheme optional for file URIs. So
this error would not happen:
$ cygstart file:/home/ricartj/page.htm
Unable to start 'file:\home\ricartj\page.htm: The specified file was not found.
The reasons for this are enumerated below:
1. Although RFC 1738 explicitly documents the double slash as
mandatory for file URIs (see Section 5), a new working draft is being
proposed:
http://tools.ietf.org/html/draft-kerwin-file-scheme-10
which makes the double slash optional (see Section 2.2).
2. Many browsers already cope with file URIs that do not contain the
double slash, I personally tested this with Firefox and Internet
Explorer. It would be great if cygstart could work like this as well.
Best regards,
