Bug reference:      5172
Logged by:          Viisard

Description:        ecpg - cursor with regexp containing '.*/' fails to
compile with gcc
Details:

I'm using ecpg (PostgreSQL 8.4.1) 4.5.0. It fails to generate valid c file,
when a cursor with a regular expression (in probably could be any string)
containing '*/'.

The line in foo.cpg:
...
EXEC SQL DECLARE foo CURSOR FOR SELECT SUBSTRING('/foo/bar','.*/');
...

is translated into:
foo.c:

    /* declare foo cursor for select substring ( '/foo/bar' , '.*/' ) */
#line 9 "foo.cpg"

    { ECPGdo(__LINE__, 0, 1, NULL, 0, ECPGst_normal, "declare foo cursor for
select substring ( '/foo/bar' , '.*/' )", ECPGt_EOIT, ECPGt_EORT);}

There is a simple workaround for this by using '.*[/]' as the regexp.

Fixed in HEAD and 8.4.
