[Libcdio-devel] S_ISLNK and S_ISSOCK error in libcdio-0.82

[carlo\.bramix]

Hello,
the newest version 0.82 cannot be compiled anymore on Mingw.
The problem happens because the tests for S_ISLNK and S_ISSOCK macros are wrong.
Into configure script it is used AC_COMPILE_IFELSE instead of AC_LINK_IFELSE.
That's a false test because it does not fail even if those macros are 
unsupported.
Infact the compiler does not generate an error, it just returns a warning like 
"implicit declaration of function S_ISLNK".
On Mingw 4.4.0 that warning is not even printed, I had to add -Wall to GCC 
options for getting it.
Attached patch fixes the problem.
Since the new version has been just released and this bug blocks the 
compilation on all platforms that do not support S_ISLNK and S_ISSOCK, do you 
think it would be possible to release a quick bugfixed revision?

Sincerely,

Carlo Bramini.
