Long list of errors from mmreg.h file

[wtrC11pgx]

I just installed Pelles C and I'm compiling a C dll on Windows 7.  Using Pelles IDE, I selected the default Windows DLL project option.  Here are the default command line options:

-std:C11 -Tx64-coff -Ot -Ob1 -fp:precise -W1 -Gd -Ze

When I compile this project, I get the following long list of errors from mmreg.h, which is an include file from the Pelles install.  Since this include file is supplied, I don't know why I get these errors.  They all appear to be related to the header file itself.

If you are compiling a Windows program, make sure you use the /Ze option!
*** Error code: 1 ***
Done.

The actual list is longer than that but the forum won't let me post the whole list. 

At the end it says to use the /Ze option, but that's part of the default compiler string shown above. 

My source code does not include mmreg.h and it has nothing to do with building a multimedia device. 

Thanks for any help on this.

Check project include files again.
For example Edit -> Find in files... mmreg.h

[wtrC11pgx]

Edit -> Find in files... mmreg.h comes up with none found.  When I remove mmreg.h from the Pelles include folder, here is the list of errors I get.  I am not including any of these headers in my C program.  My only include file is a python custom header file.  I do not include appavcap.h or mmreg.h so I don't know why these are called at all.

Python 3.6 headers don't include that appavcap.h/mmreg.h either?
Tested with Python.h and simple pyconfig.h without any errors.

Code: [Select]

#define SIZEOF_WCHAR_T 2
#define HAVE_COPYSIGN
#define HAVE_ROUND
#define HAVE_HYPOT
#define NT_THREADS
With what kind of custom python header have all those errors?

[wtrC11pgx]

Python.h is the header file for the Python C/API.  No the Python 3.6 include folder does not have those other two headers. 

"Tested with Python.h and simple pyconfig.h without any errors."  Can you show me the compiler and linker directives you used? 

Thanks. 

[TimoVJL]

Python.h is the header file for the Python C/API.  No the Python 3.6 include folder does not have those other two headers.

Somewhere is an #include for example like for vfw.h that include those files.
