[Debian GNUstep maintainers] Bug#749740: gnumail: GCC warnings that may lead to runtime issues with new GNUstep libraries

[Yavor Doganov]

Source: gnumail
Version: 1.2.0~pre3+snap20071004-5
Severity: normal
Tags: sid jessie
User: pkg-gnustep-maintainers at lists.alioth.debian.org
Usertags: gnustep-base1.24-transition gnustep-gui0.24-transition gnustep-transition

Your package builds successfully with the new GNUstep libraries, but
there are some GCC warnings that *may* lead to problems at runtime and
may affect the forthcoming gnustep transition/jessie release.  Latest
versions of the core GNUstep packages are available at mentors.d.n [*];
they will be uploaded to experimental first.

Please note that the warnings may be unrelated to GNUstep or changes in
GNUstep but could be legitimate nevertheless.  In case the fix is
applicable for the current gnustep-* library packages in sid (-base/1.22
and -gui/0.20) you can upload the fixed package before the transition
begins.  Otherwise, please wait for the transition to complete and
do not forget to adjust the Build-Depends field accordingly:

  libgnustep-base-dev (>= 1.24.6)
  or
  libgnustep-gui-dev (>= 0.24)
