commit 6d074ce231772c66e648a61f6bd2245e7129d1f5 upstream.
gcc 13 may assign another type to enumeration constants than gcc 12. Split the large enum at the top of source file stex.c such that the type of the constants used in time expressions is changed back to the same type chosen by gcc 12. This patch suppresses compiler warnings like this one:
