Comment (by knarf):

 Thank you for the very detailed bug report. This is indeed very helpful.

 As to how to fix this: if we assume that we cannot influence (to some
 degree) how users compile the code, what is left is either defining a
 strdup() ourself and thereby making sure it is always present, or
 consistently use Util_Strdup) instead of strdup(), essentially doing the
 same.

 In terms of compiler options we could require std=gnu99, and also
 recommend -Werror-implicit-function-declaration (for gcc), but would not
 be enforceable and still leaves users out in the cold.
