For a lead in on this. I have filed a bug on GCC with the -Wall option
(4558). It flags the true MININT value as a warning. Reading the GCC
manual it actually describes this as a non bug, an ISO requirement to
analyse the number first. I think it probably should not with the
explicit caste before hand.
I will have to patch the Open Office program that builds the *hdl file
to use the same logic as limits.h (-(MAX_INT)-1). All this to
compile -Wall without many messages.
On this, there is a warning I think I understand but I would like
someone to tell me why this is is a warning and what the possible
consequences are.
/data/office/solver/638/unxlngi3.pro/inc/cppuhelper/propshlp.hxx:584:
warning: `class cppu::OPropertySetHelper' has virtual functions but
non-virtual destructor
Lifes little challenges...

Hi Ken,

This brings me back to the original question. How does
unxlngi3.pro/inc/com/sun/star/awt/VclWindowPeerAttribute.hdl get created?
KenF
Usually all *.hdl files are C++-headers generated from a UNO registry by
cppumaker. The complete process is as follows:
Somewhere there is a IDL file (a likely candidate for <project> might be
'offapi'):
<project>/com/sun/star/awt/VclWindowPeerAttribute.idl
From that idlc produces a VclWindowPeerAttribute.urd, which gets merged by
regmerge into a <something>.rdb, from which finally a applicat.rdb gets
created and delivered in 'drafts'.
That 'registry database' file contains all the UNO Types known to the
OpenOffice.org application.
Later cppumaker is invoked to generate the C++ headers for type
com.sun.star.awt.VclWindowPeerAttribute from this rdb. For higher-level
modules this usually is taken care of in module 'offuh' ('uh' <=> 'UNO
Headers').
This step generates headers VclWindowPeerAttribute.hdl and
VclWindowPeerAttribute.hpp.
Note: The *.hdl contains the actual type or constant definition. The *.hpp
includes the *.hdl and contains inline implementations of member functions.
Usually user code whould include the *.hpp.
