I am trying to compile m4 2.0, and execute the following sequence:
./bootstrap
./configure
make
After a while, the processing stops with the error message
freadseek.c:69:3: error: #error "Please port gnulib freadseek.c to your
platform! Look at the definition of getc, getc_unlocked on your system,
then report this to bug-gnulib."
I've experienced this in Debian 11 and assume (but don't know) that this
is such a standard environment that I don't need to port this source
file (and if, I would have absolutely no clue what this file is supposed
to do), but that something else is not set up correctly.
Unfortunately, I have no idea where I have to start investigatin and
appreciate any pointer into the right direction.
