Dear all, shortly after the release of GNU MPC 1.3.0 we received a bug report that GCC could not be compiled any more with the new version. Indeed, one could no more include mpc.h without including stdio.h beforehand. This has been corrected in a point release 1.3.1, which is available from https://ftp.gnu.org/gnu/mpc/
We are sorry that this bug slipped through in spite of extensive testing by us and the community. Paul Zimmermann and Andreas Enge
