5.0.91 fails to compile with embedded enabled.

sql_parse.cc: In function 'int check_user(THD*, enum_server_command, const char*, uint, const char*, bool)':
sql_parse.cc:520: error: 'struct NET' has no member named 'skip_big_packet'

How to repeat:
Try to compile 5.0.91 with embedded.

Suggested fix:

This is against the publicly released 5.0.91 tarball.

Here is the bad commit:

Bug is in 5.0 only that is past EOL
[24 May 2010 22:51] Robin Johnson
It was fine in 5.0.90 and introduced in 5.0.91.

Please fix in case you make another security release like 5.0.91 was.
I've given you the patch, it's entirely trivial.
[25 May 2010 12:57] Davi Arnaut
Fixing since it was introduced in 5.0.90. Although, a new release may or may not happen.

      Bug#53908: compile failure with embedded enabled
      This fixes a recently introduced regression, where a variable is
      not defined for the embedded server. Although the embedded server
      is not supported in 5.0, make it at least compile.
