commit: ee52c156905c419323865e7cdd2deb46040f0c8a Author: Sergei Trofimovich <slyfox <AT> gentoo <DOT> org> AuthorDate: Sun Jun 23 20:50:54 2019 +0000 Commit: Sergei Trofimovich <slyfox <AT> gentoo <DOT> org> CommitDate: Tue Jun 25 06:39:27 2019 +0000 URL: https://gitweb.gentoo.org/proj/sandbox.git/commit/?id=ee52c156
scripts/gen_symbol_header.awk: undefine libc symbol aliases Avoid libc's symbol rename via #define. musl defines aliases as: #define mkstemp64 mkstemp #define mkstemps64 mkstemps This causes libsandbox's aliases to clash with one another, like mkstemp and mkstemp64. The change does not break glibc and restores musl support.
