maybe not, if I well remember I found a similar message. Anyway, to my
experience Mr. Google often has
an answer to this kind of questions (disclaimer: an answer is other than
a right answer!!!!)

http://www.ualberta.ca/AICT/RESEARCH/LinuxClusters/doc/icc91/Release_Notes.htm

at this (google-suggested) link I found:


        |libimf| Linking Change on Intel EM64T

In some earlier versions of Intel C++ Compiler, applications built for
Intel EM64T linked by default to the dynamic (shared object) version of
|libimf|, even though other libraries were linked statically. In the
current version, |libimf| is linked statically unless |-i-dynamic| is
used. This matches the behavior on IA-32 systems. You should use
|-i-dynamic| to specify the dynamic Intel libraries if you are linking
against shared objects built by Intel compilers.

A side effect of this change is that users may see the following message
from the linker:

|warning: feupdateenv is not implemented and will always fail|

This warning is due to a mismatch of library types and can be ignored.
The warning will not appear if |-i-dynamic| is used.
