Cannot use uint-declarations

[vipoty]

Describe the problem

When I try to use the declarations like uint8_t, uint16_t and so on on the second and further files in a project I have the errors:
error: unknown type name 'uint8_t'
error: unknown type name 'uint16_t'

To reproduce

Just add the second file to the project and write something like:
/* Can I use uint16_t and uint8_t here& */
uint16_t a_function(uint8_t a_variable) {
return a_variable * 2;
}

Expected behavior

uint16_t and uint8_t should be valid type declarations like in the first file in the project.
