# New package version scheme: X.Y.Z.N-R, where X.Y.Z is the GCC release (e.g.
# 4.5.4, matches gcc_version above), N is the OS/2 release (1, 2, etc) and R is
# the RPM release (1, 2, etc). The OS/2 release number increases with each
# OS/2 specific update to the sources followed by a new build, the RPM repease
# number increases with each new RPM build (which may use the same source tree
# but fix only some RPM-specific things). Note that the RPM release number
# resets to 1 each time the OS/2 release increases (which is reset to 1 in turn
# when the GCC release changes.

%changelog
* Tue Jan 30 2015 yd <yd@os2power.com> 4.9.2.1-3
- updated source code to gcc 4.9.2.
- create gccXXX forwarders to gcc1 runtime dll, use libc06 exports for
  non-standard symbols.
- use --enable-frame-pointer to disable unwinding table generation.
- build requires patched builtin.h and stddef.h (libc-0.6.6-25).
- use standard toolchain to build gcc runtime dll, use named exports only.

* Wed Nov 27 2013 yd
- Rename the following packages to avoid ABI breaks (using gcc versioning policy):
  + libstdc++ => libstdc++6
  + libsupc++ => libsupc++6
- updated source code to gcc 4.7.3.

* Mon Jul 25 2013 Dmitriy Kuminov <coding@dmik.org> - 4.4.6.17-1
- New OS/2 Release 17 of 4.4.6. See ChangeLog.OS2 for more information.

* Mon Jul 23 2013 Dmitriy Kuminov <coding@dmik.org> - 4.4.6.16-1
- New OS/2 Release 16 of 4.4.6. See ChangeLog.OS2 for more information.
- Rename the following packages to better match the conventions:
  + gcc-stack-protector => libssp
  + gcc-stdc++-shared-library => libstdc++
  + gcc-supc++-shared-library => libsupc++

* Mon Jan 09 2012 yd
- install also dlls with main package.

* Sun Jan 08 2012 yd
- moved dlls out from main package.

* Fri Dec 23 2011 yd
