-GDB's SPARC, MIPS and PowerPC targets, in 6.0, have not been updated
-to use the new frame mechanism.
+*** Build problems
 
-People encountering problems with these targets should consult GDB's
-web pages and mailing lists (http://www.gnu.org/software/gdb/) to see
-if there is an update.
+build/1411: build fails on hpux 10.20 and hpux 11.00 with CMA threads
 
-arm-*-*
+GDB does not build on HP/UX 10.20 or HP/UX 11.00 if the CMA
+thread package is installed.  The compile error is:
 
-GDB's ARM target, in 6.0, has not been updated to use the new frame
-mechanism.
+  ../../gdb/hpux-thread.c:222: variable-size type declared outside of any function
 
-Fortunately the ARM target, in the GDB's mainline sources, has been
-updated so people encountering problems should consider downloading a
-more current GDB (http://www.gnu.org/software/gdb/current).
+This happens only if the CMA thread package is installed.
+
+As a workaround, you can disable support for CMA threads
+by editing the file gdb/configure.  Find the line:
+
+  if test -f /usr/include/dce/cma_config.h ; then
+
+And replace it with:
+
+  if false ; then
+
+*** Misc
+
+gdb/1560: Control-C does not always interrupt GDB.
+
+When GDB is busy processing a command which takes a long time to
+complete, hitting Control-C does not have the expected effect.
+The command execution is not aborted, and the "QUIT" message confirming
+the abortion is displayed only after the command has been completed.
+
+*** C++ support
+
+gdb/931: GDB could be more generous when reading types C++ templates on input
+
+When the user types a template, GDB frequently requires the type to be
+typed in a certain way (e.g. "const char*" as opposed to "const char *"
+or "char const *" or "char const*").
+
+gdb/1512: no canonical way to output names of C++ types
+
+We currently don't have any canonical way to output names of C++ types.
+E.g. "const char *" versus "char const *"; more subtleties arise when
+dealing with templates.

+*** Threads
+
+threads/1650: manythreads.exp
+
+On GNU/Linux systems that use the old LinuxThreads thread library, a
+program rapidly creating and deleting threads can confuse GDB leading
+to an internal error.

+This problem does not occur on newer systems that use the NPTL
+library, and did not occur with GDB 6.1.
