+Subject: [PATCH] Fix build on musl libc
+
+On util.c the guard around #include sys/sysmacros.h prevents musl libc
+from including the file, even though musl provides the header file, thus
+failing with errors such as "call to undeclared function makedev".
+
+In procenv.c although the function makedev is used but the file
+sysmacros.h was never included, thus resulting in similar "call to
+undeclared function makedev" error hence moving inclusion sysmacros.h to
+source file from header file.
