Oh... I see. I am ignorant on what various flags mean.
Did you try to build the stand-alone/vanilla Singular configured with
'--with-apint=gmp'?
Let me summarize my problems and see if I get them right:
1) my gcc compiler confuses c and c++ programs.
I don't think so, at least not immediately. The file whose compilation
fails (using 'gcc') is supposed to be C code (and hence to be compiled
as such), but -- for whatever reason -- the Singular scripts that create
a header file (cf_gmp.h) included by that also (erroneously) include a
file (bits/c++config.h) that is simply not in the (default) search path
for header files when compiling C code.
[I don't know yet whether ArchLinux, Singular, or maybe even Sage is to
blame.]
2) I want to solve 1) by forcing sage to use the gcc-4.7.2. but the
problem is that the copy of gcc that come with sage won't build from my
system gcc...
(see the my 3rd message in this discussion)
Am I right? Any ideas on what else can I try?
Unfortunately, Singular's spkg-install is too "complex" to just manually
fix (the generated) src/factory/cf_gmp.h in a failed build and rerun
./spkg-install (from within a Sage subshell of course)... (You could
try rerunning the appropriate 'make' command afterwards though, and see
whether the remaining pieces of that target build. To resume the build
of all of Singular, you'd have to temporarily change spkg-install, or
manually issue all remaining commands, afterwards -- upon success --
manually touching spkg/installed/singular-<version>.)
But you could try to track the issue (i.e., the reason for the invalid
inclusion) further down, also by trying to build vanilla Singular 3-1-5
as mentioned above.

Well, you'd have to (at least) configure with '--with-apint=gmp' as
well
(cf. Sage's spkg-install script).
