Why would a source file have the execute bit set? In the standard library for ecliptic curve cryptography one of the C source files has the executable bit set, qv: ![enter image description here]( As you can see there are multiple C files, but only the secp2561k1.c file is executable. This is just as I downloaded it. Why would just this one source code file have its execute bits set?

There is no reason for a C source file to be executable. This may sometimes happen if the file has been transferred from or through a non-Unix operating system.

You may safely remove the execute bit if you wish:


$ chmod a-x secp256k1.c
