State-Changed-From-To: open->analyzed State-Changed-By: ljrittle State-Changed-When: Wed Mar 26 10:41:24 2003 State-Changed-Why: This is a well-known issue (and not just with FreeBSD). Although (1) it is a bug with the configure script itself to test for "feature macros" in a different context than will be used, (2) it is a libstdc++-v3 bug to not adapt to visibility of the underlying libc. I have assigned myself (and left it open) since I am reworking this aspect of the C++ library. I suspect that even after I fix (2), (1) will still present a problem for some software packages. I can confirm that this bug still exists in 3.2.2 and mainline. Thanks for the report. http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=7680
