Most compilers do not read from stdin. Also, be careful with #line -
the syntax is not 100% standardized, some compilers do not understand
#line directives generated by GNU cpp, for example.

I'd really like to know why at all compilers are so picky about file
suffixes - if a file has correct syntax, what the heck does the suffix
matter?
