There is no such thing as *the* ISO C90 compiler, but, the gcc README almost
certainly says that you need *a* ISO C90 compiler, i.e. a compiler that can
compile programs written in the C language as defined by the 1990 ISO
standard.  Gcc is one such compiler.

With whatever C compiler the gcc developer had at that time.

It probably wasn't.  The first ever compiler was most likely written
in assembler.  Later on the first compiler for a new language has usually
been written in some other language.
