Subject: cygwin choking about _impure_ptr

After my recent upgrade from cygwin 1.5.11 to 1.5.12, I often get 
a Windows pop-up error message:
> The procedure entry point _impure_ptr could not be located in the 
> dynamic link library cygwin1.dll.
I tried reinstalling a previous version, updating again, the message 
remains.
Fortunately, in most cases, the programs still run. Once, however, 
gcc would not run anymore and compiled programs didn't run either 
after this error.


On the web, I found the following message about a recent change 
that involves this entry point, might it be related?
