I've always paid for mine.  My first C compiler came with the WinNT 3.5
beta in 1992 for $99 and came with the development kit,
editor, source code debugger, tools, documentation.
A few hundred bucks is not going to hurt my business.

I have no knowledge of what state GCC was in in 1992 but it likely
did not support the MS enhancements for Win32 programming:
structured exception handling, various ABI's, inline assembler,
defined behavior for some of C's undefined behavior,
later first-class-type support for 64-bit signed and unsigned integers,
and most important:  integration with the GUI source code debugger.

You know... what a product looks like.

 I am currently in the position of needing to take some code
written for Linux/Unix and get it running in MS Windows.
 My attempts to use MSVC have been frustrating, because of some
limitations of that environment.  The two most prominent are
these:  long double is only 64 bits, and there are no integer
types of 128 bits that I could find.
 Are there any MSVC folks here who can help with these problems?
I am not an MSVC expert by any means and easily could have missed
something.

MSVC wrt windows has:
https://learn.microsoft.com/en-us/windows/win32/api/winnt/nf-winnt-interlockedcompareexchange128
But not sure about a native 128. Unless you consider:
https://learn.microsoft.com/en-us/cpp/cpp/m128i?view=msvc-170
Well, that is probably not what you are looking for as well.

 I should mention that the code is written in C, not C++, and that
is not something I am at liberty to change.
