--- Comment #6 from Jonny Grant <jg at jguk dot org> ---
Could this show the offending number in the "line number out of range" message?
And even the origin of the LINE1 macro too?

Actual:
#1 with x86-64 gcc (trunk)
<source>: In function 'main':
<source>:4:7: warning: line number out of range
    4 | #line LINE1
      |       ^~~~~
Compiler returned: 0


Expected eg:
#1 with x86-64 gcc (trunk)
<source>: In function 'main':
<source>:4:7: warning: line number 112147483647 out of range
    4 | #line LINE1
      |       ^~~~~

 LINE1 was defined in header.h:10

Compiler returned: 0



#define LINE1 112147483647
int main(void)
{
#line LINE1
}
