Most C++ compilers are based on C, because it's hard enough to make C
programs run on multiple platforms. Using C++ will increase that
incompatibility again.


AFAIK gcc will be compiled three times, until the compiler is usable on
a different platform. The bootstrap process uses the C compiler of the
platform for the first compilation, then the created compiler to compile
itself in a restricted version, and that compiler to produce the final
version. Unless you restrict your project to compile with one specific
C++ compiler, you'll have to bootstrap your compiler in a similar way.
