So it's not something we are likely able to help. But let me make some
random guess...
The problem is __gthread_cond_t has somehow become "unsigned int"
instead of pthread_cond_t. The typedef should be in
/usr/include/c++/14.2.0/x86_64-pc-linux-gnu/bits/gthr-default.h. Can
you check it?
Also maybe a previous error has caused GCC fail to find pthread_cond_t
and guess it was an "unsigned int." So if the error message isn't the
very first one you've got, find the very first error message and paste
it.
It's noticeable that your GCC configuration lacks "--disable-
fixincludes", and it's recently revealed you must remove the copy of
headers "fixed" (actually, on the contrary, I'd call it "broken") by GCC
if you've not disabled it and you've upgraded glibc (actually, any
package in general, see the "Caution"
in https://www.linuxfromscratch.org/blfs/view/10.0/general/gcc.html).
