This is "normal". gnatlib "works" on a wide variety of platforms and
there is no autoconf or anything, thus it's all very rough and basic C.
In addition, many buffers are allocated on the Ada side, and the buffer
size is not known in the C files due to a variety of very poor design
choices.
I've tried fixing this rats nest before, and got lost. I don't plan on
trying again. In part because it pisses me off that the company which
effectively owns the copyright to this part of gcc doesn't give two
shits about the "free" version or anything but their commercial
offerings.
