Got it and tried to build it. With clang-cl there is
this warning:
  jprint.c(483,40): warning: omitting the parameter name in a function 
definition is a
  C2x extension   [-Wc2x-extensions]
    483 | void jstrcache_print_stats(const char *)
        |                                        ^

With 'cl' it's an error! Simple enough to fix.
But a 'gnumake -P' on a Makefile with a multi-line macro:

define MK_TEST_C
  /*
   * A simple test for loadable .DLLs in GNU-Make.
   */
  #include <stdio.h>
  #include <stdlib.h>
  #include <string.h>
  ...
endef

generates illegal JSON:

"MK_TEST_C" : {
  "origin": "makefile",
  "private": false,
  "source": "../../Common.Windows",
  "line": 396,
  "define": "  /*
   * A simple test for loadable .DLLs in GNU-Make.
   */
  #include <stdio.h>

jsondump says ' unexpected char'. And 'jq' says:
parse error: Invalid string: control characters from
U+0000 through U+001F must be escaped at line 147, column 12
