Especially, prefer `_rmdir` on MinGW. Closes #4668.

L: C-Sources

> I also noticed that even if `_rmdir` is available in MinGW header direct.h, ModelicaInternal.c uses `rmdir` in line 388 and not `_rmdir` of line 390. Hence, it is not...

The current behavior found in Modelica.Fluid.Machines.BaseClasses.PartialPump exhibits non-physical behavior vs. changes to gravity. While "head" should change when gravity changes, the flow rate itself should not change if you change...

**Reported by rfranke on 17 Jan 2013 19:39 UTC** Modelica.Fluid generally uses the names `rho` for density and `mu` for dynamic viscosity. See e.g.: ``` Modelica.Fluid.Machines.Pump Modelica.Fluid.Pipes.BaseClasses.FlowModels Modelica.Fluid.Fittings.BaseClasses.massFlowRate_dp_and_Re ``` The...

The connect-clause "connect(RS1.qn, q)" and "connect(RS1.q, qn)" seem to be "connect(RS1.q, q)" and "connect(RS1.qn, qn)" respectively. ![connect_diagram](https://github.com/modelica/ModelicaStandardLibrary/assets/49439939/f897fad0-5857-4fe8-834d-c8d5cf0ae0ac) When simulating Modelica.Electrical.Digital.Examples.FlipFlop in MWorks.Sysplorer, the variable FF.q is not matched with JK...

What is the purpose of the protected top-level connectors in CauerLowPassOPV und CauerLowPassSC? CauerLowPassAnalog uses ordinary connects instead. https://github.com/modelica/ModelicaStandardLibrary/blob/eea74432d6006527b41676547ec2326d8bcbb8f2/Modelica/Electrical/Analog/Examples/CauerLowPassSC.mo#L46-L109 ![connectors](https://user-images.githubusercontent.com/14896695/41230706-1d1354a2-6d81-11e8-804f-5de2faaa7ea2.png)
