[Gm2] Gm2 Cygwin building problem

[dw2]

Hi Christoph,

/usr/include/stdlib.h:290:1: error: expected unqualified-id before 
‘[’ token

I think you will find after preprocessing that line contains 
[[noreturn]] and it is not supported in gcc c++ 4.7.4.

I edited my stdlib.h (it requires admin rights). Line 290 in my file now 
reads:

_VOID _EXFUN(quick_exit,(int __status) _ATTRIBUTE ((__noreturn__)));

This is consistent with other uses of noreturn in the file.


Note once that is fixed I got stuck with another error (after 91 hours):
