+
+ * hookapi.cc (rvadelta): Change argument to DWORD to eliminate a
+ compiler warning.
+
+ * path.h (path_conv::set_cygexec): New function.
+ * spawn.cc (av::iscygwin): Eliminate.
+ (av::av): Don't initialize iscygwin.
+ (spawn_guts): Just use real_path.iscygexec for all tests.
+ (av::fixup): Short circuit test if .exe extension and known cygexec.
+ Set cygexec flag appropriately if we find that program uses cygwin1.dll.

* dcrt0.cc (initial_env): Don't attempt stracing if dynamically loaded.
