It doesn't work if you have set CYGWIN=check_case:strict:

No more fun with check_case:strict?

Ok.  I'll fix this.  I hated seeing all of the upper case DLL names
provided by Windows 95 but it if breaks strict case checking then
I guess I'll have to live with this.

Btw, you realize that CYGWIN=check_case:strict is likely to cause
a real drag on cygwin performance, right?

I've uploaded a gdb-20010428-3 which removes a strlwr from gdb, so
now you get to see all of the dlls in their strangely cased glory.

I hope this fixes the strict case checking problem.

I have serious problems here with the performance of my box, I suggest
check_case:strict was one part in the puzzle to increase it.
The box at my bureau is about two or three times faster mainly when
running e.g. configure.  I suggest a problem with harddisk IO or s.th.
related.

Since my two harddisks (34GB together) are complete full (about 4GB
free space ar five partitions), I suggest it might be a problem
because I never defragmented it a whole year long now.  I didn't found
a free defragmenter for my 'Loreley', which is my box at home.  I
found a defrag tool for my WS, but this tool refuses to work on NT
Server (got a server, you can pay...).

So it is s.th. hardisk IO related.  I excluded several other causes
with little registry fixes which always speeds up everything a little,
but it is still three times slower as my box in the office.

Anyone is aware of good defrag tool for NT4.0 Server?

Sorry, I read this mail a second time now...
Did you ask for the long version of s.th.? --->>> s.ome.th.ing.
Is there a usual way to write it shorter? Maybe 'STH'?

It seems to be that I'm the only one using check_case:strict?
Or is my NT which is messed up?

I don't know how to fix this.  I'm not randomly inserting capitalization
here.

If the filenames returned by the
system don't match the actual filenames in the system then I'm
not going to go out of my way to figure them out.  I don't even
know *how* I'd figure them out.

It does. Couldn't you just ignore the settings for check_case loading the
DLL's in GDB? It seems, that the problems only arises when simulating
Windows internal file operations. Windows does not take care of the case
anyway, so why should Cygwin? The check_case is "just" for ported Unix apps
that do not know of this Windows internal behaviour. They may only use the
functionality (loading a depending DLL) as service out-of-the-box, GDB is
therefore just an exception.

Jorg

Oh yes.  That's right.  I think I even resisted this patch, mainly because
I could not believe that Windows was really that stupid.

I have a hard time with the idea that I have to add Windows-specific code
to gdb at this point.  I had an ITS (In The Shower) experience today and
realized that, of course, I could use the FindFirstFile technique to
get the right filename and your email confirms that.

This is a really hard change to make, though.  It will be like typing in
molasses getting this patch into gdb.  It just feels so wrong.

remember my cygpath patch for -S? I'd actually requested the directory a
