Heh heh heh, I sent that before the build finished.  I should learn...

The only thing we can use is -ansi.  Either of the C90/94[*] variants
mean that '//' comments aren't recognized.  The table in c-decl.c sets
the same flags when -ansi or -std=iso9899:1990 are given, but -ansi is
clearly being looked for additionally elsewhere.

[*] Clause [1.2] seems to want the language in C89/C90 with the library
    in C94.
