Syntax is easy, well once you have fully working preprocessor too, but how
about libraries? How will you convert scanf/printf/puts/etc? What if it uses
3rd party libraries?

Only at the surface. There are many semantics differences that's not
convertible at all. e.g.: ALL C expressions are potentially a boolean
expression which in turn has boolean value, while in Pascal, only boolean
expression has boolean value. At syntax level, there's no Pascal equivalent
of C's comma (sequence) operator. Argument evaluation in C is strictly right
to left, in Pascal it's up to the compiler. A silly but valid C statement:

printf("%d%d%d\n",i++,++i,++i,i++);

would be hard to convert to Pascal automatically without blowing out the
compiler.
