When cross-building for vxworks, test for declarations of long double functions in math.h. We don't normally test for these functions when cross compiling, because link tests don't work, or ever really, but not defining them as available causes replacements to be defined in ways that may cause duplicate definition linker errors if the units defining both the replacement and the actual implementation are brought in because of other symbols. for libstdc++-v3/ChangeLog * crossconfig.m4 (GLIBCXX_CROSSCONFIG) [*-vxworks*]: Define long double functions as available if declared by math.h. (GLIBCXX_CHECK_MATH_DECL, GLIBCXX_CHECK_MATH_DECLS): New. * configure: Rebuild. From-SVN: r279731 |
