When defining POSIX_SIGNALS in config.h, C-g is interrupting a lisp
infinite loop.


Details of what I did:
----------------------
* first, configure emacs (as previously) and build emacs.
* reproduced the bug (while t) not interruptible.
* edited config.h in src directory, adding 
  #define POSIX_SIGNALS 1
 just after the #define EMACS_CONFIG_H
* make emacs again
* test again => C-g is interrupting.
* tested what the pre-processing was giving.
 The calls to UNBLOCK_ATIMERS are replaced by
 sys_sigunblock ((sys_sigmask (14))) ;
