Implicit make woes

Obviously something is set wrong ($INCLUDE or similiar), but the more I
fuss with this the worse it gets. Explicit compiling is fine:
bash-2.02$ gcc hello.c -o hello.exe
bash-2.02$ ./hello
hello GNUish world!
But an implicit make (single source, no makefile) yields:
bash-2.02$ rm hello.exe
bash-2.02$ make hello
/bin/gcc.exe hello.c -o hello
hello.c:1: No include path in which to find stdio.h
make: *** [hello] Error 1
bash-2.02$
I tried moving stdio.h to /usr/include, but that just changed the
error. I will probably reinstall, but I'd like to know why make should
foul up a simple compile.
