About AC_CHECK_HEADERS and different locations

[Sergio Belkin]

Hi,

I am autoconfiscating a project that has a header file with a line:

#include <postgresql/libpq-fe.h>

configure.ac has:

AC_CHECK_HEADERS(postgresql/libpq-fe.h)

The problem is that Ubuntu has such a header file on
/usr/include/postgresq  but fedora has it on  /usr/include. So how can
I make that configure script checks  for differents paths?

Thanks in advance!
