+// mkdtemp() wasn't declared in <stdlib.h> until NDK r9b due to a simple
+// packaging bug (the function has always been implemented in all versions
+// of the C library). This header is provided to build Breakpad with earlier
+// NDK revisions (e.g. the one used by Chromium). It may be removed in the
+// future once all major projects upgrade to use a more recent NDK.
+//
+// The reason this is inlined here is to avoid linking a new object file
+// into each unit test program (i.e. keep build files simple).
