Re: Buiiding LO6.1.4.2 with pdfium emits “error: invalid conversion from ‘int’ to ‘boolean’ [-fpermissive]”

Hello,

the problematic call is:

S=/src/libreoffice-6.1.4.2 && B=$S/build && I=$B/instdir && W=$B/workdir &&  mkdir -p
$W/GenCxxObject/UnpackedTarball/pdfium/core/fxcodec/codec/
$W/Dep/GenCxxObject/UnpackedTarball/pdfium/core/fxcodec/codec/ && cd /src/libreoffice-6.1.4.2 &&

/usr/local/include/glib-2.0 -isystem
/usr/local/lib64/glib-2.0/include -isystem /usr/local/include   

When I pass -E to the compiler, it prints:

# 317 "/usr/local/include/jmorecfg.h" 3 4
typedef enum { FALSE = 0, TRUE = 1 } boolean;
# 28 "/usr/local/include/jpeglib.h" 2 3 4

So #include "jpeglib.h" implies #include "jmorecfg.h" and libreoffice-
6.1.4.2/build/workdir/UnpackedTarball/pdfium/core/fxcodec/codec/fx_codec_jpeg.cpp does #include 
"jpeglib.h".

This code:
typedef enum { a = 1, b = 2} c;

c x () {  return 2;}

also fails compiling with 
error: invalid conversion from ‘int’ to ‘c’ [-fpermissive]
 c x () {  return 2;}
                  ^
jmorecfg.h comes from jpeg9-c.  jpeg-turbo-1.5.3 has another jmorecfg.h, where boolean is defined 
as int.
