ECPG and escape strings

ECPG seems to be a little overzealous with the new escape string syntax:

% cat foo.pgc
int
main(void)
{
putchar('\n');
return 0;
}

% ecpg foo.pgc

% gcc -I`pg_config --includedir` -c foo.c
foo.pgc: In function `main':
foo.pgc:4: `E' undeclared (first use in this function)
foo.pgc:4: (Each undeclared identifier is reported only once
foo.pgc:4: for each function it appears in.)
foo.pgc:4: syntax error before character constant

% cat foo.c
/* Processed by ecpg (4.1.1) */
/* These include files are added by the preprocessor */
#include <ecpgtype.h>
#include <ecpglib.h>
#include <ecpgerrno.h>
#include <sqlca.h>
/* End of automatic include section */
#line 1 "foo.pgc"
int
main(void)
{
putchar(E'\n');
return 0;
}
