It appears that stack overflow checks for recusrive stored procedure
calls, that run in the normal server, did not work in embedded and were
 dummified with preprocessor magic( #ifndef EMBEDDED_SERVER ).
      
 The fix is to remove ifdefs, there is no reason not to run overflow checks
 and crash in deeply recursive calls. 
      
 Note: Start of the stack (thd->thread_stack variable) in embedded is not
necessarily exact but stil provides the best guess. Unless the caller of 
mysql_read_connect()   is already deep in the stack, thd->thread_stack 
variable should approximate stack  start address well.

The bug was that ./configure was  passing paramers to subscripts as $@, and to handle embedded spaces it needs
to be quoted as "$@".
This resulting into a bug when ./configure was called e.g with CFLAGS='-m64 -Xstrconst'..

Additionally, fixed cmake/configure.pl did not handle environment variables passed on the command line.
this is fixed in this push

Fix contains of :
-  splitting CC/CXX if there are more that 2 space-delimited tokens, add the rest to CFLAGS
(in this case CC was set to "ccache gcc --pipe", and this broke recognition of gcc compiler
as CMake understands CC consisting of 2 space delimited tokens but not more)

-  add my_new.cc to mysys fle list if C++ operator new is not found. Always, not only
for gcc  (the original problem was that missing operator new when compiling with CXX=gcc)

The patch is ready and will be pushed via -bugfixing.

There was an erroneous parameter when calling flush_master_info
from write_ignored_events_info_to_relay_log which could lead to a
server crash. This happens because the I/O thread releases the
log_lock before calling the flush_master_info.

Set the function to call flush_master_info with third parameter
to true, so that the mutex is properly taken.

The task is to 
  (a) add a comment on indexes and 
  (b) increase the maximum length of column, table and the new index comments.

The patch committed on behalf of Yoshinori Matsunobu (Yoshinori.Matsunobu@Sun.COM).

Fix configure.js : set the variabes in cache, so they can overwrite cache variables in CMakeLists.txt

Removed --remove_file in cleanup procedure

- mysql_install_db is in scripts dir now
- sql-bench is installed
-some extra support-files (e.g ini) are in support-files
