+Subject: [PATCH] Fix musl build: basename() is in libgen.h.
+
+Also, its argument is not const, so add const_cast. This is risky
+because in fact basename() will modify the argument if it ends with /
+but that's not the case here.

+Subject: [PATCH] Fix use of LONG_BIT
+
+LONG_BIT is not a sysconf value, it is either 32 or 64. Using it as
+a sysconf value will give weird results.
+
+Originally it was sysconf(_SC_LONG_BIT) (before it was "fixed" by the
+gentoo guys). But this is useless: it will always return a value
+equal to LONG_BIT: it's either compiled 32-bit or 64-bit so a runtime
+lookup doesn't make sense. For this reason, musl has removed the
+definition of _SC_LONG_BIT.
