--- Comment #4 from joseph at codesourcery dot com <joseph at codesourcery dot com> 2012-04-07 16:06:46 UTC --- My previous suggestion stands of having the compiler predefine __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS, whether for C++11 or generally for C++, to make all existing stdint.h headers work as desired. You could predefine in the compiler, or you could predefine in stdint-wrap.h when it includes a system stdint.h and remove the conditionals in stdint-gcc.h. (In the header might be better because then you can use #ifndef to avoid any conflict with a user's definition of those macros.) If the libstdc++ people conclude that these definitions should be present for all C++ versions, not just C++11, then the conditionals in glibc's stdint.h can be removed at leisure (the predefines in GCC will make the conditionals useless but harmless).
