That's where your error lies.  It is not a colorization, but an
encoding in utf-8 of the characters ‘ and ’:

my_test.c: In function ‘main’:
my_test.c:58: error: expected ‘;’ before ‘x’

I see no missing character here.

Configure the same encoding in your terminal and in your shell!


If your terminal handles UTF-8:

[pjb@hubble :0.0 tmp]$ export LC_CTYPE=en_US.UTF-8
[pjb@hubble :0.0 tmp]$ cc  -c -o a.o a.c
a.c: In function ‘main’:
a.c:3: error: expected ‘;’ before ‘x’


If your terminal handles ISO-8859-1:

[pjb@hubble :0.0 tmp]$ export LC_CTYPE=en_US.ISO-8859-1
[pjb@hubble :0.0 tmp]$ cc  -c -o a.o a.c
a.c: In function 'main':
a.c:3: error: expected ';' before 'x'

etc...
