linux下编译交叉工具链的工具源码

file which is then compiled, you can use line control to inform the
compiler about where each source line originated).

You should install this package if you are a C programmer and you use
macros.

%package gnat
Summary: Ada 95 support for GCC
Group: Development/Languages
Requires: gcc = %{version}-%{release}, libgnat = %{version}-%{release}
Obsoletes: gnat-devel, gcc3-gnat
Prereq: /sbin/install-info

%description gnat
GNAT is a GNU Ada 95 front-end to GCC. This package includes development tools,
the documents and Ada 95 compiler.

%package -n libgnat
Summary: GNU Ada 95 runtime shared libraries
Group: System Environment/Libraries
Obsoletes: gnat libgnat3

%description -n libgnat
GNAT is a GNU Ada 95 front-end to GCC. This package includes shared libraries,
which are required to run programs compiled with the GNAT.
