Hi, I'm getting this error from the compilation of PrettyPrinter

``` CC pretty_printer_la-PluginEntry.lo In file included from /usr/include/unicode/umachine.h:52, from /usr/include/unicode/utypes.h:38, from /usr/include/unicode/ucnv_err.h:88, from /usr/include/unicode/ucnv.h:52, from /usr/include/libxml2/libxml/encoding.h:31, from /usr/include/libxml2/libxml/parser.h:810, from PluginEntry.h:32, from PluginEntry.c:28: PrettyPrinter.h:55:22: error: two or more data types in declaration specifiers 55 | typedef unsigned int bool; | ^~~~ In file included from PluginEntry.h:34, from PluginEntry.c:28: PrettyPrinter.h:55:1: warning: useless type name in empty declaration 55 | typedef unsigned int bool; | ^~~~~~~ make[3]: *** [Makefile:664: pretty_printer_la-PluginEntry.lo] Error 1 ```

I guess that this may be because the bool type is defined somewhere else? Removing the typedef and including stdbool.h fixed it for me, but AFAIK it requires C99.
