size_t is highlighted as a built-in type, but it is not listed on "C type specifiers" help page
It is defined in a couple of files, but right-clicking on it doesn't show "Go to definition of: size_t"
If Pelles C treats size_t as a built-in type - it should be on "C type specifiers" help page and perhaps "Storage of basic C types" too,
if it should be a definition - it should not be hightlighted as built-in type, and should have "Go to definition of: size_t" option when right-clicking on it.
