[Bug c/24119] New: gcc-4.x fails to build on AIX 5.2.0.0-ML04

["h dot m dot brand at xs4all dot nl" <gcc-bugzilla@gcc.gnu.org>]

Building gcc-4.x (anything post 4.0.0-20040919) fails for me on AIX 5.2
First problem is a missing -bbigtoc to the loader, causing a message like

gcc -B/usr/local/ppc64/bin   -g -DENABLE_CHECKING -DENABLE_ASSERT_CHECKING -DIN_
GCC   -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -

but that would probably not promote to the build I am attempting to complete

Second problem appears after that fix:

FWIW that gcc-4.0.0 passed all tests, and is still used in my smoke tests for 
the perl development branche, at which it still passes all tests
