This is indeed a mystery to me. Perhaps the people working
with cygwin and related matters, such as tcl/tk and dejagnu
thereunder, on cygwin list have any comments?

My e-mail to David had this question in it:

-----
Hello David.

I'm just curious, how did you get the testsuite running?

I always get can't find /usr/share/dejagnu/runtest.exp
regardless if I set DEJAGNULIBS as /usr/share/dejagnu or
something like /cygdrive/c/cygwin/usr/share/dejagnu...

Oh, I have a win2k/pro/sp1 with an up to date cygwin-1.1.7.

Cheers,

/ChJ

and it was because of his "report" to the gcc-testresults list

http://gcc.gnu.org/ml/gcc-testresults/2000-12/msg00326.html

I'm quite interested in hearing about how to get dejagnu/tcl
working more "properly" under cygwin, i.e., I can have cygwin
installed wherever I want to, like the recommended C:\cygwin,
and still be able to run the GCC testsuite.

TIA for any comments.
