[Proj] Errors compiling proj4 on linux

[Calogero Mauceri]

Hi Martin,

The problem happens just running ./configure without passing any option.
Here is a snapshot of the configure log

...
checking for ANSI C header files... (cached) yes
checking jni.h usability... yes
checking jni.h presence... yes
checking for jni.h... yes
checking whether to enable Java/JNI support... enabled
...

so it seems that it automatically enabled Java/JNI even if I do not pass 
--with-jni option.

If I try to compile the proj from svn trunk, In the configure output JNI 
seems to be still enabled

...
checking for ANSI C header files... (cached) yes
checking jni.h usability... yes
checking jni.h presence... yes
checking for jni.h... yes
checking whether to enable Java/JNI support... enabled
...

but the compilation gives me some errors related to JAVA like:

...
jniproj.c: In function `Java_org_proj4_PJ_getSemiMajorAxis':
jniproj.c:221: error: `NAN' undeclared (first use in this function)
jniproj.c: In function `Java_org_proj4_PJ_getSemiMinorAxis':
jniproj.c:237: error: `NAN' undeclared (first use in this function)
....

Thanks,
     Calogero.
