It appears that many targets include the map header transitively in other std headers included from system.h. However there are some editions of clang/libc++ in Xcode that do not, which results in a bootstrap fail - since when resolver.h is included there is then a conflict in declaring abort(). The fix is to ensure that map is pulled in by system.h and before resolver.h is included. As a precautionary measure and to alert anyone perhaps adding another header to resolver.h this patch also gates the direct includes there on !IN_GCC. c++tools/ChangeLog: * resolver.h: Do not include std headers directly when building in GCC. gcc/cp/ChangeLog: * mapper-client.cc (INCLUDE_MAP): New; require map to be included from system.h. * mapper-resolver.cc (INCLUDE_MAP): Likewise.
