• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

Thanks for your patience, just a heads-up that I've now beginning to look into this PR, thanks a lot as always :)

Since glib releases new versions fairly frequently, the amount of additional patches to maintain this PR adds is not ideal.

1. Could these be and have you perhaps already shared these patches upstream as well?
2. Could some of the less stable patches be replaced with a replace_in_file() or a save(..., append=True) call?

Hi @klausholstjacobsen - thank you for your contribution. While we're happy to support platforms beyonds the one covered by our CI service, this PR introduces patches to C/C++ code that goes beyond we can validate. We don't know to what extent this was tested or validated, and we would not offer this to our users without minimal due diligence.

I would strongly suggest that the changes needed to support QNX 7.0 are proposed upstream to the glib maintainers, rather than the Conan Center recipe. If these patches already exist in an upstream version, please mention this in the PR description for traceability, along with a justification for backporting them to all other older versions.

Otherwise, I'm afraid this is not something we would be inclined to consider for merge.

@jcar87 You are absolutely correct. I was just sitting this morning contemplating this.
I have thus chosen to remove all patches related to qnx 7.0 as I cannot verify the origin
The good news is that the patched code is already built into qnx 7.1, so glib will build for qnx 7.1 with only a few remaining modifications to the recipe!
