  bug#27741: udf test fails on AIX < 5.3
  
  problem #1: udf_example.so does not get built on AIX
  
  solution#1: build it yourself using
  cd sql; gcc  -g -I ../include/ -I /usr/include/ -lpthread  \
  -shared -o udf_example.so udf_example.c; mv udf_example.so \
  .libs/ 
  
  problem#2 (the bug): udf_example fails because it does not
  recognize the variable LD_LIBRARY_PATH when doing dl_open(),
  it looks at LIBPATH
  
  solution#2: add the library path to LIBPATH
  
  problem#3: udf_example returns the wrong result length since 
  it relies on strmov to return a pointer to the end of the 
  string that it copies. On AIX builds, where m_string.h is not
  included (m_string defines a macro expanding strmov to stpcpy),
  there is a macro expanding strmov to strcpy, which returns a 
  pointer to the first character.
  
  solution#3: define strmov as stpcpy.
  
  problem#4: #2 applies on hp-ux as well, but this platform
  looks at SHLIB_PATH
  
  solution#4: added the library path to SHLIB_PATH

    bug#27741: Added library paths to LIBPATH ( shared library 
    path environment variable used on AIX) and
    SHLIB_PATH (ditto on hp-ux)

  sql/udf_example.c@stripped, 2007-05-31 14:22:19+02:00, mhansson@stripped +2 -1
    bug#27741: define strmov as stpcpy rather than strcpy and 
    include string.h. The definition for strmov in the standalone 
    case was not maintained properly

# This is a BitKeeper patch.  What follows are the unified diffs for the
