The c99 program on Void Linux

Today I found there is a c99 program in Void Linux:

$ c99
cc: fatal error: no input files
compilation terminated.
$ which c99
/usr/bin/c99

Check what it is:

$ file /usr/bin/c99
/usr/bin/c99: POSIX shell script, ASCII text executable
$ cat /usr/bin/c99
#!/bin/sh
exec /usr/bin/cc -std=c99 "$@"

Um, just a shell script which invokes /usr/bin/cc. So check cc program:

$ ll /usr/bin/cc
lrwxrwxrwx 1 root root 3 Jun  9 05:32 /usr/bin/cc -> gcc

Oh, a link to gcc.
