scripts/gen_symbol_header.awk: undefine libc symbol aliases |
| 9 |
|
| 10 |
Avoid libc's symbol rename via #define. musl defines aliases as: |
| 11 |
#define mkstemp64 mkstemp |
| 12 |
#define mkstemps64 mkstemps |
| 13 |
|
| 14 |
This causes libsandbox's aliases to clash with one another, |
| 15 |
like mkstemp and mkstemp64. |
| 16 |
|
| 17 |
The change does not break glibc and restores musl support. |
