Is there a problem with stdio.h? Or is it just gets()?
When I use gets() the compiler throws a warning #2018:
Undeclared function 'gets;' assuming 'extern' returning 'int'.

If I add my own prototype: ' char* gets ( char* );'  it compiles OK.

Use compiler -std:C99 and you see 'warning #2241: The function 'gets' is marked as deprecated.'
PellesC isn't C89 compiler.

Compatibility
The most recent revision of the C standard (2011) has definitively removed this function from its specification.
The function is deprecated in C++ (as of 2011 standard, which follows C99+TC3).
