On my Linux 2.2.24 system with gcc-2.95, building for
cs4236, support/isapnp will not build. After, the configure
in Makefile.conf has:
.
.
.
CONFIG_ISA = y
CONFIG_ISAPNP_KERNEL =
CONFIG_ISAPNP = y
.
.
.
If I apply the following patch after the configure, I get the correct build.

===========================================================================
The patch to Makefile appears to be necessary, because CONFIG_ISAPNP_KERNEL
is no longer set to 'n' when it's false.
The second part appears to be necessary because otherwise -fno-common seems to
require that support/isapnp_proc.c be patched this way:
================================================================

#include "isapnp.h"
void *isapnp_alloc(long size);
! struct isapnp_card *isapnp_cards;
! struct isapnp_dev *isapnp_devices;
struct isapnp_info_buffer {
char *buffer; /* pointer to begin of buffer */
--- 50,57 ----
#include "isapnp.h"
void *isapnp_alloc(long size);
! extern struct isapnp_card *isapnp_cards;
! extern struct isapnp_dev *isapnp_devices;
struct isapnp_info_buffer {
char *buffer; /* pointer to begin of buffer */
======================================================================
I'm not sure the best way to fix this, but the first patch above
is what I'm using to get the snd-isapnp.o module built.
