I got another buildbot notification and as far as I can tell it has nothing to do with my last commit. The stdio output is at http://buildbot.scipy.org/MacOSX%20x86/builds/49/step-shell/0 And the errors seem to be of this sort: _configtest.c: In function 'main': _configtest.c:4: error: 'isnan' undeclared (first use in this function) _configtest.c:4: error: (Each undeclared identifier is reported only once _configtest.c:4: error: for each function it appears in.) _configtest.c: In function 'main': _configtest.c:4: error: 'isnan' undeclared (first use in this function) _configtest.c:4: error: (Each undeclared identifier is reported only once _configtest.c:4: error: for each function it appears in.) _configtest.c: In function 'main': _configtest.c:4: error: 'isinf' undeclared (first use in this function) _configtest.c:4: error: (Each undeclared identifier is reported only once _configtest.c:4: error: for each function it appears in.) _configtest.c: In function 'main': _configtest.c:4: error: 'isinf' undeclared (first use in this function) _configtest.c:4: error: (Each undeclared identifier is reported only once _configtest.c:4: error: for each function it appears in.) I haven't had any problems compiling on my own machine. Chuck
