fix -std=c23 build failure

[heitbaum]

gcc-15 switched to -std=c23 by default:

https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=55e3bd376b2214e200fa76d12b67ff259b06c212

As a result mumudvb fails the build so only typedef int bool for STDC_VERSION <= 201710L (C17)

    ../../src/mumudvb.h:136:47: error: expected ';', identifier or '(' before 'bool'
      136 |     typedef enum { false = 0, true = !false } bool;
          |                                               ^~~~

Hello
Thanks for your fix
It seems though with the logic that there is a risk that it does not run with Clang

https://stackoverflow.com/questions/66954583/why-clang-running-on-windows-has-no-c-conformance-stdc-is-not-defined-to-1

Do you think there is a way to invert the logic so it does work as before unless version is defined and > than xxxx

Thank you

I’m not sure on clang and windows. But an alternative that should work on c99 compiles (and does work with gcc-15 is)
