compiler warning on freebsd

[Markus Moeller]

Hi,

 I have an application which compiles fine on Linux, but on FreeBSD I get 
the following warning.  What might be the reason that it fails on FreeBSD ?

gcc -DHAVE_CONFIG_H -I.    -I/usr/include  -I/usr/local/include  -g -O2 -Wall 
 -Wno-unknown-pragmas -Wextra -Werror -Wcomment -Wpointer-arith 
 st-align -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations 
 -Wdeclaration-after-statement -Wshadow -MT support_  o -MD -MP -MF 
.deps/support_sasl.Tpo -c -o support_sasl.o support_sasl.c


/usr/local/include/sasl/sasl.h:349: warning: function declaration isn't a 
prototype
