GCC 4.7.2 is the first bug-fix release containing important fixes
for regressions and serious bugs in GCC 4.7.1 with over 70 bugs
fixed since the previous release.
A notable change in GCC 4.7.2 compared to 4.7.1 are ABI bug fixes
related to some C++11 templates (std::list and std::pair). As a result,
code using those templates in C++11 mode is again ABI compatible with
code in C++03/C++98 mode or C++11 mode of GCC 4.6 and earlier, but might
be ABI incompatible with code compiled by GCC 4.7.1 or 4.7.0 in C++11
mode. See http://gcc.gnu.org/gcc-4.7/changes.html for more details.
This is the list of problem reports (PRs) from GCC's bug tracking system
that are known to be fixed in this release. This list might not be complete
(that is, it is possible that some PRs that have been fixed are not listed
here).

${MACHINE_GNU_PLATFORM} by default and already used in
gcc47-libs/buildlink3.mk.

Note that because the default for GCC_TARGET_MACHINE _should_ be the
same as the 'gcc -dumpmachine' output theres no need for a revbump.
is the minimum version for gcc47 and gcc47-libs.
Remove BUILDLINK_ABI_DEPENDS.gcc47-libs as its now redundant.
This fixes the case where USE_PKGSRC_GCC_RUNTIME=yes and gcc-aux is needed
(In that case _GCC_REQD is 20120614, the version number of gcc-aux) as
pointed out by Jonathan Perkin.
This package contains _just_ the shared libraries from gcc47 that programs
compiled with gcc need at runtime so that the entire gcc47 package does not
have to be install.
Because multiple packages cannot be build from the same PKGDIR and building
components of gcc separately is problematic this package is build using a
a couple of "cheap tricks":
1) gcc47 is built as before (including the libraries) but with a second
RPATH compiled in to all programs.
2) This package has a BUILD_DEPENDS on lang/gcc47 and simply copies the
shared libraries (except the java ones) to the second RPATH location
(so as to not have conflicts with lang/gcc47).
3) When adding a runtime dependence the pattern '{gcc47,gcc47-libs}>=4.7.*'
is used (i.e. the full gcc47 OR the gcc47-libs package can be used).
4) So that when a package that has the above dependence is installed
pkg_add will, if neither gcc47 or gcc47-libs is installed, automatically
install gcc47-libs the PKGREVISION of gcc47-libs should all ways be
bumped so that it is at least 1 more than that of the lang/gcc47
package. (With a note in this packages Makefile and one to be placed
in lang/gcc47's Makefile.)
