in case of error, the conftest.c code should be given

[Vincent Lefevre]

The configure script for MPFR was generated by GNU Autoconf 2.69.
When I do "./configure CC=tcc", I get the following error in
config.log:

[...]

If you meant to cross compile, use `--host'.
See `config.log' for more details

then variables and confdefs.h, but no conftest.c code.
The conftest.c file is no longer there.

So, it's impossible to know what's wrong.
