"missing separator" error when making on Solaris 10 X86

A few days ago I first wrote about this problem on the mailing list, 
but gave not enough details. Sorry for that. Here is all the 
information regarding the case.

I am trying to compile the stable 1.4 release of Kannel on a fresh 
installed Solaris 10 X86. I am using the default gcc 3.4.3 compiler 
you find in /usr/sfw/bin  , and gmake 3.80 dowloaded from Sunfreeware
(http://www.sunfreeware.com). 

The configure phase seem to complete successfully, but when I run 
make I get this:

===
bash-3.00# /usr/local/bin/make
Makefile:315: .depend: No such file or directory
for dir in gw gw/smsc gwlib test utils wmlscript checks wap radius; do \
        gcc -D_REENTRANT=1 -I. -Igw -g -O2 -I/usr/include/libxml2 -MM $dir/*.c |
sed "s:^[^ ]:$dir/&:"; done > .depend
utils/start-stop-daemon.c:93:2: #error Unknown architecture - cannot build
start-stop-daemon
.depend:1: *** missing separator.  Stop.
===

If you read carefully you see that the error is that the first line of the
.depend file misses a separator. The top of the file appears like this:

===

"/export/home/giacecco/gateway-1.4.0/" is the directory with the 
distribution of Kannel, of course.

I then removed the lines starting with "gw/#", and the make completed
successfully, and I am now running Kannel with no problems. Any idea 
about why this happen? Thanks.
