I suppose I could find out by looking more deeply into the component
(which looks nice in the README), but I'm lazy today, so I ask: do you
have a way of capturing the standard-error stream from a process, in
addition to the standard-output stream?

With the process 'Start' subprograms, you can provide your own input/output/error pipes. If not provided they default to the standard pipes.
function Start (Command : in String;
Working_Directory : in String := ".";
Input : in Pipe := Standard_Input;
Output : in Pipe := Standard_Output;
Errors : in Pipe := Standard_Error;
Pipeline : in Boolean := False) return Process;
The ''Results_Of' function returns 'Command_Results' which provide access to data from both the Output_Pipe and the Error_Pipe.
In hindsight, this is not adequate. I will review over the weekend and attempt a better solution.

Atm, the code uses Florist for 'POSIX' and one function from 'GNAT.OS_Lib'.
Florist appears to be gnat-specific ...
"FLORIST, an Ada application program interface for operating system services for use with the GNAT compiler and the Gnu Ada Runtime Library (GNARL)."
I have no means of testing on Windows. I hope that it may be possible to use with cygwin or a similar compatibility layer.

What is the advantage over using the compiler-supplied libraries to do these things?

Florist is an implementation of a standard for Ada-POSIX bindings,
https://www.iso.org/standard/34354.html, so the Florist API should not
be GNAT-specific.
However, the implementation of Florist may depend on the underlying
system, including the Ada compiler and the OS.
Using the Florist API, rather than using GNAT libraries or OS functions
directly, should increase the potential portability. Actual portability
will depend on the existence of implementations, for the target system,
of Florist or other realizations of the standard Ada-POSIX binding.

Ability to provide input data.
Ability to provide input/output/error pipes.
Ability to pipeline processes.
Several convenience functions to simplify the above.
Potential for increased portability.

Some time ago, I gathered some information about compilers providing
support of the Ada-POSIX standard for this Wikibooks article.

Thank you for this info. Most encouraging.

An interesting idea. No support for HAC atm. I'm currently in the
middle of improving support for task safe OS commands. Once done, I'll
look into HAC support, probably via polyorb, of which I am quite fond.
