Re: GDB for powerpc-eabi under cygwin

[Joćo Cadamuro Junior <cadamuro at lit dot cpdtt dot cefetpr dot br>]

After "fighting and fighting", I fix the problem in building GDB under cygwin 1.1.6.

Firstly, the problem was cygwin, not GDB. This was discovered when I tried to build the insight-5.0
release and it fail in the same point as 2000-11-30 snapshot.

So, after a number of workarounds without success, I decide to work as a typical Windows user -
remove cygwin and install it all again.

After that, I rebuild all my tools (binutils, cross compiler, libraries and debugger) and ...
works!!! Also the second problem described with breakpoints in the SDS target disappeared (for now
I'm using SDS target for 2 days without seeing the problem again...).

After all, I think I have a corruption in some cygwin upgrade, because since version 1.1.2 I only
upgrade my cygwin installation.

Thank you for all the people who inverst their precious time in taking a look into my problem.
Special thanks to Michael Chastain for the help with the PowerPC simulator, whose problem wasn't
cygwin.

I hope this can help more cygwin users in the future...
