Hi

I'm afraid that PREPARE of ecpglib is not thread safe.
The following global variables are modified without any locking system.
Is it unnecessary worry?

  [interfaces/ecpg/ecpglib/prepare.c]
  static int  nextStmtID = 1;
  static stmtCacheEntry *stmtCacheEntries = NULL;
  static struct declared_statement *g_declared_list;
