trouble in setting environment variables for cygwin app

[maxpagani]

Hi everyone,
I would like to use Netbeans to develop and debug a cygwin application on Windows.
The problem I face is that my application needs the PATH environment variable to include /usr/bin and /usr/local/bin in order to find the DLLs it needs (otherwise I get the error 0xc0000135 on debugging start).
I added the variables in the Project/Properties/Run/Environment widget, but they are not apparently applied to the gdb session.
I added the variables to the Windows environment using the Windows pathnames (hoping for someone in the middle to translate them), but still I get the same problem.
What's odd, is that if I chose "run Main Project" the application starts properly, while "Debug Main Project" always fail.

I'm using Netbeans 7.1.2; Windows 7 64 bits; cygwin with gdb v7.3.50.

Is there any additional information I can provide?

Thank you in advance

Best Regards
