Bug#1075535: src2tex: ftbfs with GCC-14

[Marek Benc]

Hello,

Here's a patch that adds the missing includes, function declarations,
and the return value for main().

Best Regards,
Marek
Description: Fix build on GCC-14
 Fix several warnings that were turned into errors in GCC-14:
   * Implicit declaration of functions
   * Implicit return type for main function
