New submission from Diego Alonso :
Trying to build Python 3.10 on Ubuntu 20.04. It builds everything but the fcntl
module; ie. at the end it says:
Failed to build these modules:
fcntl.
Here are the compilation errors. It's trying to use certain macros that are
undefined: I_PUSH, I_POP, I_LOOK, I_FLUSH, I_FLUSHBAND, I_SETSIG, I_GETSIG,
I_FIND, I_PEEK, I_SRDOPT, I_GRDOPT, I_NREAD, I_FDINSERT, I_STR, I_SWROPT,
I_SENDFD, I_RECVFD, I_LIST, I_ATMARK, I_CKBAND, I_GETBAND, I_CANPUT,
I_SETCLTIME, I_LINK, I_UNLINK, I_PLINK, I_PUNLINK
