Hello

I building the 5.1.61 from source and becomes the following error

I use glibc 2.3.6 with linuxthreads, all version before build fine, in version 5.1.61 the source signal_handler.cc was new


include -I../include -I../../include -I../../regex -I../../sql -O2 -march=i486 -fno-implicit-templates -fno-exceptions -fno-rtti -MT signal_handler.o -MD -MP -MF .deps/signal_handler.Tpo -c -o signal_handler.o ../../sql/signal_handler.cc

I can solve this issue with the following patch.

define UNSAFE_DEFAULT_LINUX_THREADS 200 copied from 'mysqld.cc'
