[ **] The RPC code is not 64 bit clean. This is getting slowly fixed
but expect incompatible changes on 64 bit platforms like Alpha.
+[ **] If a DSO is using implicitly libpthread and the application itself
+ does not there is a name lookup problem. E.g., the function fork()
+ will be found in the libc.so instead of libpthread since the thread
+ library is behind the libc. To correct this problem it must *not*
+ be relied on the currently still enabled handling of weak symbols
+ in the dynamic linker. Instead explicit tests for the availability
+ of the libpthread version are needed. [PR libc/2325]
+
[ *] The precision of the `sinhl' and/or `asinhl' function do not seem
to be the best.
