To check RTEMS/newlib/gcc for issues related to portability and to 
compliance to c-/c++ standards, I occasionally build RTEMS using 
different types of "-std=..." flags in CFLAGS, with "-ansi" and 
"-std=c99" being the extremal corner cases [1].

I.e. I am deliberately trying to provoke issues gcc's and RTEMS's 
"liberal" default cflags try to hide away from users.

During these attempts, "//" comments in c-files add (fairly minor) 
nuissances, which could easily be avoided by contributors not using them.


[1] The sad and unpleasant truth is, there are parts in RTEMS and it's 
toolchain (esp. newlib) which are neither c89/c90 nor c99 compliant, 
which means neither of these cases works smoothly.
