mISDN fails to compile

Hi,

At last have I come around to play with mISDN again.
Today I downloaded the latest version from git (git-clone git://git.misdn.org/mISDN.git/).
Configure went OK but when I try to do "make modules" I get the following error:

export MISDN_INC=/usr/local/src/mISDN/standalone/include; export MISDN_CFLAGS="-D_MCONFIG_MISDN -D_MCONFIG_MISDN_DSP -D_MCONFIG_MISDN_L1OIP -D_MCONFIG_MISDN_HFCPCI -D_MCONFIG_MISDN_HFCMULTI"; make -C /lib/modules/3.2.12-gentoo/build  _MCONFIG_MISDN=m _MCONFIG_MISDN_DSP=m _MCONFIG_MISDN_L1OIP=m _MCONFIG_MISDN_HFCPCI=m _MCONFIG_MISDN_HFCMULTI=m SUBDIRS=/usr/local/src/mISDN/standalone/drivers/isdn/mISDN modules
make[3]: Entering directory `/usr/src/linux-3.2.12-gentoo'

/usr/local/src/mISDN/standalone/drivers/isdn/mISDN/socket.c:26:12: error: 'THIS_MODULE' undeclared here (not in a function)

Any suggestion of misconfiguration on my part or a workaround?

Oh, by the way, this system is running on kernel 3.2.12 at the moment.
