Subject: [PATCH] don't make __errno_location / __h_errno_location hidden
|
|
|
|
Closes #2089 (https://bugs.busybox.net/show_bug.cgi?id=2089)
|
|
|
|
__errno_location / __h_errno_location access has to go through the PLT
|
|
like malloc/free, so the linuxthread variants gets used instead when
|
|
compiling with -pthread.
|
|
|
|
Based on http://github.com/mat-c/uClibc/commit/328d392c54aa5dc2b8e7f398a419087de497de2b
