apt-cyg fails gcc install due to postinstall script not having execute privileges set

[GoogleCodeExporter]

What steps will reproduce the problem?
1. On a Cycgwin install without gcc. Install gcc.  

What is the expected output? What do you see instead?
The postinstall script should run. However, you will get access denied error 
when apt-cyg attempts to run the postinstall script.

What version of the product are you using? On what operating system?
Most recent SVN.
Cygwin on Windows 7.

Please provide any additional information below.
This is a simple problem. Execute privileges are not set for the gcc 
postinstall script. I added a chmod line to set them for each post install 
before running it. I assumed the same problem could occur for remove scripts so 
I did it there as well. All works great now. I've attached a simple patch to 
implement this fix.

Also experiencing this—quite annoying given that gcc is a relatively 
important package.

Patch works. Found this problem today and changed apt-cyg according to this 
patch.
