Subject: OS X has the PAM library, but only 10.6 has the headers, so check for those.  NOTE... 
X-Git-Tag: v1.0.90~165
X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=ee770d0d1e31b5ef0344415bee04d9e87ac56679;p=tigervnc.git

OS X has the PAM library, but only 10.6 has the headers, so check for those.  NOTE: a compiler check is forced because, when cross-compiling on 10.6 using the 10.5 or 10.4 SDK, the preprocessor will detect the headers in /usr/include, but the compiler can't compile them, since the SDK does not have those headers.
