-Fix build on platforms where __USER_LABEL_PREFIX__ is not empty
-
-On most platforms, a C language symbol and its assembly equivalent are
-identical. However, on the Blackfin architecture, this isn't the case,
-the corresponding C language symbol in assembly is prepended with a
-"_". Blackfin therefore has __USER_LABEL_PREFIX__ defined to "_".
-
-Cairo already has some code to cope with __USER_LABEL_PREFIX__, but
-this code isn't completely correct: it prepends both assembly symbols
-and C symbols with __USER_LABEL_PREFIX__, which cannot work.
-
-This patch fixes that by using the existing slim_hidden_asmname() to
-define assembly symbols, and introduce a new slim_hidden_realname()
-for C symbols.
