I have compiled gdb-7.2 out-of-the-box using stock djdev203 and djdev204.  Both
builds were successful.  I was able to step through a simple sample program
using the djdev203 build but for the djdev204 build this was not possible.
I got the following output:

I do not understand why the 2.03 version understands that the target is an exec
but the 2.04 version does not.  If I specify the target the I get the following
output:

Any suggestions?  I have configured and compiled out-of-the-box on WinXP Prof SP3.
gcc 4.4.4 and bash 2.05b release 3.  If more info is need please let me know.
