[Lazarus] Make of revision 57762 failing under Raspbian

[Joe]

On Raspberry Pi 3B+ computers under Raspbian Stretch 20180418 with 
Lazarus 1.6.2 installed I tried to compile the current development 
revision 57762 of Lazarus.
It failed in 'grids.pas', line 4150, with error 'identifier idents no 
member "Width"'.

This I did:
(1) Created directory '~/lazarus'.
(2) svn co https://svn.freepascal.org/svn/lazarus/trunk lazarus
(3) cd lazarus
(4) svn update
(5) make bigide

What's wrong? Is it a mistake of the operator or a software bug? Should 
I file a mantis report?
