Error: parse error before '.' & number of arguments doesn't match

Question

Compiling my simple source code reports error error: parse error before '.' . But in fact there is not any "." token on this line.
At my guess it has something to do with JNI C macros but I really have no idea how to find that bug
// ##net_java_dev_jssm_MulticastSSM.h: line 55
JNIEXPORT void JNICALL Java_net_java_dev_jssm_MulticastSSM_join2
  (JNIEnv *, jobject, jstring, jstring);
// ##net_java_dev_jssm_MulticastSSM.c: line 306
JNIEXPORT void JNICALL Java_net_java_dev_jssm_MulticastSSM_join2
  (JNIEnv *env, jobject obj, jstring s_addr, jstring g_addr) {
// no code yet
mingw32-gcc.exe -DWIN32 -Wall -c -IC:\java\JNI_headerFiles\jdk1.6.0/include -IC:\java\JNI_headerFiles\jdk1.6.0/include/win32 -shared src_c/net_java_dev_jssm_MulticastSSM.c -DNODEBUG

src_c/net_java_dev_jssm_MulticastSSM.h:56: error: prototype declaration
make: *** [all] Error 1
C compiler: mingw32-gcc.exe
JNI: jdk1.6.0
Any help would be really appreciated.

Hi radone,
I just read your posting and suddently got an idea why your compiler was complaining about the period. In most C environment, there is a definition
#define s_addr S_un.S_addr
in some socket-related header file! Now you know where the dot is coming from.
