gettimeofday is a UNIX function that doesn't exist on every system. 

Grep for it in SConstruct and in the source code. Since it doesn't exist on all systems, SConstruct SHOULD test for it, and define HAVE_GETTIMEOFDAY_H or something, then the sources should #ifdef HAVE_GETTIMEOFDAY. 

Better yet, change the code to use only the ANSI C runtime library calls.

Alternatively, it may exist on your system but is not being found. Grep in your system header files as well, and if you find it, add the directory to your custom.py.

Speaking of which, the custom.py usage has changed. There are default mingw-custom.py etc. for different platforms.

Hope this helps,
Mike

Gettimeofday is a POSIX function

References in

./Top/threads.c where is is used in #if defined(LINUX) || defined(WIN32)
./Top/csound.c where it is protected with HAVE_GETTIMEOFDAY
