Huh, it's not a question of gcc vs cc, it's that meson automatically uses
ccache. And it looks like msys's ccache is broken at the moment (installed
yesterday):

$ ccache --version
ccache version 4.4.1
...

$ echo > test.c
$ ccache cc -c test.c
Segmentation fault (core dumped)
..

not sure how that leads to hanging, but it's not too surprising that things
don't work out after that...

Greetings,
