I was looking at support for UNC file paths in the eCos Configuration Tool today. The convoluted #! magic we use in our Tcl scripts to find a Cygwin Tcl shell is getting in the way when calling (eg) heapgen.tcl via a UNC repository path. This code is only needed to support installations of Cygwin that are more than 5 years old.
Rather than increase the complexity of the #! magic still further, I think it now makes sense to revert to a simple "#! /usr/bin/tclsh" within our Tcl scripts. However, this would break compatibility with old Cygwin installations providing only tclsh8*.exe or cygtclsh80.exe. Any objections? John Dallaway
