This seems an issue with tcc. The following line shows where that error happened.

$ sed -n 177p /data/data/com.termux/files/usr/include/string.h
size_t strxfrm(char* __BIONIC_COMPLICATED_NULLNESS __dst, const char* _Nonnull __src, size_t __n);

And __BIONIC_COMPLICATED_NULLNESS macro is defined as

$ grep -ir "define __BIONIC_COMPLICATED_NULLNESS" /data/data/com.termux/files/usr/include/
/data/data/com.termux/files/usr/include/sys/cdefs.h:#define __BIONIC_COMPLICATED_NULLNESS _Null_unspecified

So, tcc could not recognize _Null_unspecified attribute.

====

tcc git fails for me on termux/aarch64 in similar manner. Does this sounds like preprocessor issue?
