Dear Alexei,

Oh, Oh. I found my misunderstanding.
ftconfig.h does like this:
#if defined( _WIN32 ) && ( defined( _DLL ) || defined( DLL_EXPORT ) )
#define FT_EXPORT( x ) __declspec( dllexport ) x
#elif defined( __GNUC__ ) && __GNUC__ >= 4
#define FT_EXPORT( x ) __attribute__(( visibility( "default" ) )) x
#elif defined( __cplusplus )
#define FT_EXPORT( x ) extern "C" x
#else
#define FT_EXPORT( x ) extern x
#endif
Thus, attribute visibility is only enabled for GCC >= 4.
Comparing with configure.raw, I guess you assumed that
-fvisibility is GCC-specific feature?
# I should remind, such kind of linker-related technologies
# in GNU toolchains are heavily inspired by Solaris, maybe
# in Drepper's era.
