[Pkg-postgresql-public] Bug#750163: postgresql-plproxy: Conflicting declarations of function plproxy_yy_scan_bytes to cause undefined behaviour

[Peter Eisentraut]

The flex documentation has

    Function: YY_BUFFER_STATE yy_scan_bytes ( const char *bytes, int len)

which is what plproxy abides by.

The actual flex implementation uses yy_size_t, which is really size_t.

Reported upstream as <https://sourceforge.net/p/flex/bugs/184/>.

Ideally, flex --header-file should be used instead of copying the declaration.

Patch proposed upstream as <https://github.com/markokr/plproxy-dev/pull/10>.
