	* src/SDCCval.c: Preserve signed integer values when converting a
	  constexpr initialiser from integer to float type (bug #4144).
	  Obtain the value as double through floatFromVal, which respects
	  the source integer type's signedness. Leave integer conversions
	  unchanged.
	* support/regression/tests/bug-4144.c: Test six failing return-context
	  conversions and six cases that pass before and after the fix.
