Problem with GMP configuring during building

[milan radulovic <radulovic_milan at yahoo dot com>]

Hi Yann, Arnaud, All,

few weeks ago I successfully built the cross compiler for target mips-unknown-linux-uclibc.

Then, I tried to build the cross compiler for other target mips-unknown-linux-gnu and the building failed on Installing GMP step, the substep Configuring GMP as you can see below:

After that I tried to rebuilt again for target mips-unknown-linux-uclibc, but unfortunately I got the same problem, and now I cannot build crosscompiler for any target....

Could you tell me what is the cause for the this problem?

Thanks.

Milan
