Until now, the ./meta/guile was not mentioned anywhere, and therefore it
was not obvious how to run the locally compiled Guile without installing
it.

While modifying the file, I took the liberty to also mention a bit about
compiling Guile using Guix.

Finally, the header lines where cleaned up, ensuring all of them end at
70 and have a leading space.

* HACKING (Hacking It Yourself): Add Guix instructions.  Add a note
about meta/guile script.
(Sample GDB Initialization File),
(Naming conventions): Clean up the header line.
---
v2:
Add note regarding JIT and GNU Hurd.  Add note regarding -fexcess-precision.
Add --disable-static and explain it.

Previous discussion happened on the mailing list.

+You can spawn a shell with all the required dependencies using GNU Guix
+by running the following command:

+    guix shell -D -f guix.scm --pure

+In this way, you can effortlessly compile Guile from the Git checkout

Much welcome addition!

I would suggest running:

  guix shell -CP

(Currently ‘README’ suggests ‘guix shell’.)

The rationale is: it’s shorter, using a container avoids interference,
and ‘-P’ works well with ‘config.cache’ & co. (because the cached file
names then are $HOME/.guix-profile/…).

WDYT?

Thanks,
Ludo’.

v3:
Use -CP instead of --pure.

Modified as agreed on irc.  I am not convinced on the -P, but I defer to your
judgment on this.

Have a nice day,
