Bug 937412 – dev-cpp/yaml-cpp-0.8.0: [gcc-15] error: ‘uint16_t’ was not declared in this scope

• Status: UNCONFIRMED
• Product: Gentoo Linux

[Description tdr 2024-08-05 23:55:27 UTC]

package failed with gcc:15 on emitterutils.cpp with multiple messages:

    error: ‘uint16_t’ was not declared in this scope emitterutils.cpp 
    +
    note: ‘uint16_t’ is defined in header ‘<cstdint>’

Reproducible: Always

Steps to Reproduce:
enable gcc:15 compiler

emerge =yaml-cpp-0.8.0
