A nit: it should be okay to require C99 for the compiler, but we should not require that for the library (including header files), because MinGW, for example, uses a C99-compliant GCC, but the headers and the function from the standard C library are those from Windows, which are not 100% C99.
Gnulib doesn't assume 100% C99, only the common features that I think even Microsoft supports nowadays. (Even C11 is not 100% C99 compatible....)
