+Subject: [PATCH 04/15] Windows: Use '/' not '\' in progpath and leave case
+ as-is
+
+Windows can handle both '/' and '\' dirseps. GCC will
+have been built using Cygwin, MSYS* or cross-compiled
+from a system where dirsep is '/' so it is cleaner to
+force the dirseps to be '/' and keep the case as-is.
+
+This way, the value will be consistent with the build
+system and string operations, be they internal to GCC
+or external to it (e.g. processing map files with sed)
+have a better chance of working as expected.
+
+A concrete instance of when this matters is when cross
+compiling GNU/Linux glibc on Windows.
