Rather the ask is not going to be fixed, the symbolic link trick works, even
more you can make a new directory which symbolic links from the gcc sources
toplevel directory and then have the GMP symbolic link there.  So if GCC
sources can still be in read only directory if needed.

Oh the version of GMP/MPFR/MPC is already printed out for a long time now.

[Bug bootstrap/40447] New: Add a switch to configure to allow *source* directory of mprt and gmp to be specified.

[david dot kirkby at onetel dot net]

It's currently possible to build gcc in two ways. 
1) Compiler and install mpfr and use switches to indicate the location of their
instalation

--with-mpfr=/somedirector --

2) Put directories mpfr and gmp under the source of gcc. 

What I propose is to allow a couple of extra switches

--mpfr-source-dir= & --gmp-source-dir=

Apart from making installation easier, it would mean anyone doing a 'gcc -v'
would know what versions of the mpfr and gmp were used.

You can use soft links inside the source directory to say where the source
directories are located.  Is that good enough?

That's what I did. 

The real benefit I see is that someone could see what versions of the gmp and
mpfr were used to configure gcc. So if they wanted to build it the same, they
would have a much better chance. It would also be quicker to do. 

I guess it depends on the amount of worked needed to the configure.ac to
determine if this is sensible or not.

GCC already outputs the version of GMP/MPFR:
GNU C (GCC) version 4.5.0 20090519 (experimental) [trunk revision 147718]
(i386-apple-darwin8.11.1)
        compiled by GNU C version 4.5.0 20090519 (experimental) [trunk revision
147718], GMP version 4.2.2, MPFR version 2.4.1

I assume this is only in your experimental version. I can see that is an
improvement. I still think the switch would be useful, but it does reduce the
need for it somewhat.

Older versions show the information too:

$ echo | gcc -v -x c -c - 2>&1 | fgrep -B1 GMP
GNU C (GCC) version 4.3.2 (i686-pc-linux-gnu)
        compiled by GNU C version 4.3.2, GMP version 4.2.3, MPFR version 2.3.1.
