Tooling failure with Intel 11.1 in tools/project_to_continuous_main.cpp

Tooling fails with Intel 11.1 on CX1 giving:

project_to_continuous_main.cpp(35): error: identifier "size_t" is undefined
    void project_to_continuous(const char *, size_t, const char *, size_t);
                                             ^

project_to_continuous_main.cpp(35): error: identifier "size_t" is undefined
    void project_to_continuous(const char *, size_t, const char *, size_t);
                                                                   ^

compilation aborted for project_to_continuous_main.cpp (code 2)
gmake[1]: *** [project_to_continuous_main.o] Error 2
make: *** [fltools] Error 2

This looks like a header ordering issue needing stdlib.h moving higher.
