Yes. Here is from egcs faq:

You may get errors with the X driver of the form
_X11TransSocketUNIXConnect: Can't connect: errno = 111
It's a kernel bug. The function sys_iopl in arch/i386/kernel/ioport.c does an
illegal hack which used to work but is now broken since GCC optimizes more
aggressively . The newer 2.1.x kernels already have a fix which should also
work in 2.0.32.
-- cut --
Since I am not using 2.0.x kernels I am could not check situations with them
by myself, but in FAQ 2.0.32 is mentioned and only one file so I am was shure
that in 2.0.33 this is fixed... 2.1.89+ works just fine (I am test 2.1.89,
2.1.90, 2.1.92 & 2.1.94 by myself with binutils 2.8.1.0.23 & pgcc 1.0.2).
