John,
error_code.cpp contains the following #defines:
#define _CRT_SECURE_NO_DEPRECATE #define _SCL_SECURE_NO_DEPRECATE
It should first check that these macros are not defined already. Otherwise users who #define these macros on the command line will received duplicate definition errors, as I am. Also, you might consider adding:
#define _SECURE_SCL 0
for VC 9.
I'ld rather have it somewhere in Boost.Config. Every library has to deal with these, so why not silence the warnings once and for all.
I thought we'd been through this: defining those in a header is *too late* to do any good, these global macros have to be set either by the build system, or at the top of a .cpp file *before* any headers are included, in the latter case there should also be a check that they weren't previously set on the command line.
Sorry, I missed that discussion. Is the build system expected to support these anytime soon? Regards Hartmut
