You are right: After loading the binary it says "initialising...". After 1
Minute 30 seconds (!) it turns to "ready" and I can work normally.

I tried again with "gdb --annotate=3" (= without binary as parameter) and
loaded the binary with
(gdb) file binary.bin
There was no "initialising..." message visible and I could start
immediately. What's the difference ?

Would this qualify as "large" ? ;)

Hmm, not sure. I just compiled with gcc-2.95 (yes, that old....) and "-g".
"info gcc" gives me the impression that this means stabs or gdb ...

Not that old...

"gud-tooltip-mode is a variable defined in `gud.el'.
Its value is nil"

So it is turned off.
Many thanks for your help :) For the time beeing, I'll just load the
binary from within gdb. Everything seems to work and I don't have to wait
1:30 minutes. If my colleages see this, I will have to hear their laughter
till the end of days ;)
