MPS issue job000646

TitleBuilds on FreeBSD stopped working
Assigned userNick Barnes
DescriptionMPS builds on FreeBSD have stopped working because <stdlib.h> now includes prototypes for functions like long long strtoll(const char *, char **, int). This function, and the long long type, are in C99. But gcc -ansi -pedantic is C89. There doesn't seem to be a way to tell gcc to talk C99.
There isn't any preprocessor directive to turn off the relevant parts of stdlib.
Incidentally, this file in FreeBSD -current seems to conditionalize the long long stuff according to whether the compiler speaks C99. But that hasn't made it onto the -stable branch of FreeBSD, which broke this way on 2001-03-02: <> and has been broken in FreeBSD releases since 4.3.
AnalysisShould the MPS be compiled with a C89 compiler or a C99 compiler? If the former, what should we do about system header files such as this one, which is C99 only? In the meantime, we can use fri4gc.gmk to turn off the -pedantic compiler option.
