Cygwin gdb 7.0 build configure error


Hello,

I downloaded the source code. Under cygwin, I have got an error when I run
./configure. Here it is:

awang <at> fmcna ~/gdbSrce/gdb-7.0
$ ./configure --target=powerpc
./configure: line 27: syntax error near unexpected token `$'\r''
'/configure: line 27: `esac

Could anyone help me out? The cygwin is the latest release. Thanks.

have gdb go until SIGSEGV including at the start/end?


I have a program with a race condition.
On Windows it hits an access violation eventually if I run it in a loop (like very 400 runs).
I want to test it on a Unix system (e.g. GNU/Linux or MacOSX or Solaris or OpenBSD).

On Windows I use:

foo.cmd:
 <at> echo off
setlocal
set a=1
:loop
echo %a%
\bin\x86\cdb -g -G foo.exe
set /a a=a + 1
goto :loop

 
this runs my program in a loop, in a debugger, until it hits an access violation.
It prints how many times it has run before each run.
 -g means go right away at the start of the process 
 -G means go past the end of the process 
 By default the debugger stops on access violation (SIGSEGV).
 set /a is for "arithmetic" (expression evaluation) 

 
What is the equivalent with gdb/sh? (Or at least gdb).
I've tried a bit with -x and -batch, no luck.
