works... but only for cygwin dejagnu...
It doesn't on the dejagnu I found for msys system :(
After a looong debugging, it seems to turn out to be because
(on msys)$ runtest --version
WARNING: Couldn't find the global config file.
Expect version is 5.26
Tcl version is 8.4
Framework version is 1.4.2.x
while on cygwin:
$ runtest --version
Expect version is 5.45
Tcl version is 8.5
Framework version is 1.5
Which leads to the fact that remote_spawn directly calls spawn in 5.26,
while it uses open command in version 5.45...
The problem is that only the open command returns a channeled suitable for
fconfigure...
which leads to the following error on msys:
ERROR: tcl error sourcing ../../../puresrc/gdb/testsuite/gdb.base/co1.exp.
ERROR: can not find channel named "6"

"catch "uplevel #0 source $test_file_name""
Any suggestions, other that throwing away the old dejagnu ...
Of course, if someone as a more recent dejagnu for msys,
I am all for it!
