[uclibc-ng-devel] [PATCH] stdlib: increase number of static atexit handlers to 32

From: Yann Le Du <yann.le.du(a)kernkonzept.com> The existing limit of 20 was found to be insufficient when moving from gcc 8 to gcc 9. At the time a test ran already 16 handlers had been installed leaving only minimal room for application installed handlers. Musl uses 32, as does newlib. Further, the ISO C standard for C99 specifies that: The implementation shall support the registration of at least 32 functions.
