* Usually, Scintilla will now be built with -O2
* this can improve performance significantly over the standard Scintilla -Os
(up to 10%).
* this also allows link-time-optimizing both Scintilla and SciTECO
(which are linked statically) by adding -flto to CFLAGS, CXXFLAGS and LDFLAGS.
Link-time-optimization will both reduce the total binary size
and improve performance slightly since scintilla_send_message() can be
inlined.
An -O3 optimized Scintilla when linked with LTO results in an only 300kb
larger SciTECO binary.
* the highest possible optimization thus requires the following maintainer
flags on the ./configure command line:
CFLAGS="-O3 -mtune=native -march=native -flto"
CXXFLAGS="-O3 -mtune=native -march=native -flto"
LDFLAGS="-flto"
* Windows and Debian builds use link-time-optimization now.
On Windows - where we link in everything statically - building
the dependant libraries with -flto could improve performance
even more.
* Debian builds respect the default hardening flags of the build
server now. This should ensure that SciTECO is built for the
correct architecture at the recommended optimization level etc.

* it also sets the compatibility level to 7 which was required
when building for Ubuntu Lucid. This version cannot be supported
however since its libglib version is too old.
|
|
this should simplify building SciTECO for new users
* compiler and archiver are passed down from Autoconf,
so cross-compiling should work transparently
* `make clean` will also clean the Scintilla source tree
* there is no longer any need for "source bundles" as
tar balls also contain Scintilla/Scinterm now
* building from Git is not much more difficult than building
from a tar ball
* The versions of Scintilla/Scinterm embedded as submodules
already contain all the patches necessary (currently none are
necessary), so there's no need to have patch files in the
repository
* INSTALL instructions have been rewritten
* the --with-scintilla and --with-scinterm site-config options
have been kept. But they should be rarely necessary now.

so no additional --with-scintilla is necessary when building from
a source bundle
|
|
* prepared for upload to Ubuntu PPA
* debian package will not be in autoconf source distro
* will only build as a non-native package based on a source bundle
that contains scintilla, scinterm and has patches applied
