It is to the extent that the GNU C compiler is portable because GNU C++ 
is essentially just a preprocessor: it generates C, which is then fed to 
the GNU G compiler to produce an executable. 

There are a number of other languages that are part of the GNU Compiler 
Collection: C++, Objective-C, Fortran, Ada, and Go. In addition, similar 
third-party front ends exist for Pascal, Modula-2, Modula-3 and PL/I and 
COBOL.

I have no knowledge of other platform-independent languages apart from 
two: 
- K&R C on OS-9/68000 The C source was immediately compilable with
  both GNU and Borland C compilers, but the libraries were quite
  nonstandard, so this forced incomparible code changes on both targets.  

- Borland C and C++ for Windows 95. A long time ago I made an effort to
  learn Borland C and C++. IIRC the languages themselves were quite
  standards-compliant (I never tried to port them to other systems, but
  their non-standard support libraries made applications written with
  them non-portable. 

From the above experience I've learned that portability depends on two 
things: 

- how closely the compilers follow the language specification

- in the case of 'small' languages such as C, C++ and Java, 
  where a lot of their power comes from their standard libraries,
  portability also depends on the availability of standard libraries
   on both original and target os/hardware platforms.
