build fails with format errors about esppdp

[leifj]

One example:

/home/leifj/esppdp/firmware/main/pdp11_rq.c:3286:58: warning: format '%d' expects argument of type 'int', but argument 3 has type 'uint32' {aka 'long unsigned int'} [-Wformat=]

Use the older 4.x esp-idf. esp-idf 5.x introduced some extra code checks, which lead to this error.

Best use is esp-idf 4.3, since 4.2 didn't had the 'esp_bt.h' and 4.4 introduced some different usage of the IRAM, so the project don't fit in default config.

Dear Sprite_tm,

You have done a stunning job here of stripping Simh down to produce a suitable image for the ESP32. I have looked into this in the past and given up in despair! So I built a much simpler PDP11 emulator. Anyway, the only problem with the repo is as above in that trying to build this with IDF 5.0 generates lots of errors (warnings). I have attached a rather dubious patch to sort this out. In addition, I have also changed some of the options in sdkconfig. I have attached this file as well as the format has changed from IDF 4->5. The final image now runs fine on my Wrover kit.

@Isysxp Thanks for the patch! Unfortunately, it seems to be misformed, I can't get it to apply (patch says 'Only garbage was found in the patch input.' and on casual inspection at least the filenames to patch are missing)

[Isysxp]

Well, this is embarrassing. I used WinMerge to create this patch and apologies as there does not seem to be any way to use patches in this format!!!! So, I have created a fork with the updated code which I hope is OK. I would note that this is not a brilliant solution and there are still many build warnings. However, it is adequate for anyone using the latest IDF install.

[Spritetm]

Sure, if you can tell me where the fork is, I can pull from that, or you can see if you can create a pull request myself.

I have created it in https://github.com/Isysxp/esppdp.
