Bug 947100 – sys-devel/bc-1.07.1-r6: fails to compile with musl /gcc15 - getopt.c:1135:1: error: conflicting types for 'getopt'; have 'int(int, char * const*, const char *)'

• Product: Gentoo Linux
• Status: UNCONFIRMED ---

[Description meartzheast877 2024-12-28 09:14:14 UTC]

sys-devel/bc crash if you try to compile it using musl and GCC 15. It seems to be the same error of getopt()

Reproducible: Always

Steps to Reproduce:
1. Have a musl system
2. Install GCC 15
3. Try to compile sys-devel/bc
Actual Results:  
The program cannot be compiled

Expected Results:  
It should have compiled and installed successfully.
