Hi Jacques,
I think you are looking for SIGSTP or SIGSTOP but I think that's
not exactly it. From what I know you cannot do that for emerge
easily. For similar results you might want to set up ccache.

If you really mean just interrupting a compile, then you should be able
to stop with Ctl-C, and then start/continue by running make or ninja
again, assuming that is what is used for whatever you are compiling.
Ccache can help since most of the results of the previous compile
attempt will have been cached, and so will be completed more quickly
the next time, but it's not the same as continuing from where it was
interrupted.
If, as Filip implies, you are asking about interrupting emerge, it's
easy enough to interrupt, but essentially impossible to continue from
where it left off. "emerge --continue" will just try to emerge every
package from the interrupted emerge which was not completed, but it
will start each one from scratch. What has often, but not alwasy
worked for me, is to use ebuild directly. "ebuild
.../path/to/package.ebuild compile" will figure out that everything
prior to the compile was completed, and then issue the make or ninja
commands, which will just pick up where they left off. If that does
work, then you need to repeat the ebuild, but with the install and then
the qmerge commands. The only problem with that (for me, at least) is
that ebuild does not leave exactly the same lines in emerge.log, so a
package installed that way will not show up in "gentlop -t package"
output.
