Failing LO build with Raspberry pi4 (-Werror,-Wformat in idl)

[Julien Nabet]

Hello,

On Raspberry pi4 with master sources updated today + make clean, I got:

[CXX] sax/source/expatwrap/sax_expat.cxx
/home/pi/lo/libreoffice/idl/source/prj/database.cxx:437:23: error: 
format specifies type 'unsigned long' but the argument has type 
'sal_uInt64' (aka 'unsigned long long') [-Werror,-Wformat]
              "error", nRow, nColumn );
                       ^~~~

IMHO I think it's related to

tdf#114441: Convert use of sal_uLong to better integer types

I use:

CC=clang
CXX=clang++

Raspbian clang version 11.0.1-2+rpi1
Target: armv6k-unknown-linux-gnueabihf
Thread model: posix
InstalledDir: /usr/bin

Any idea to fix this?

Regards,

Julien
