make: *** [obj/nfcdrom_linux.o] Error 1 
 

Reproducible: Always
Steps to Reproduce:
emerge -v aranym 
 
Actual Results:  
compilation failure. 

Expected Results:  
correct compilation 

New aranym version (0.9.0) has same problem. This looks like a conflict between 
glibc and kernel-headers.

I've been trying to find a fix for it but couldn't so far.

1. Easy way to reproduce bug: 
--- test.c --- 
#include <linux/types.h> 
#include <sys/select.h> 
-------------- 
$ gcc -c test.c 
In file included from t.c:2: 
/usr/include/sys/select.h:78: error: conflicting types for 'fd_set' 
/usr/include/linux/types.h:22: error: previous declaration of 'fd_set' was here 
 
If you change header include order --- everything will go just ok. 
 
2. In file src/natfeat/nfcdrom_linux.cpp move "#include <linux/cdrom.h>" to 
LAST include. Bug will be fixed.  
 
Sorry, I'm currently in a hurry and have no time for normal patch. 

Thank you for the fix Nickolay I have commited it to CVS. Sadly I ran into
another problem with 0.9.0, it didn't compile fvdi.prg.bz2 which caused the
install to fail, but 0.9.0_beta2 works again.

aranym-0.9.0.ebuild

I simply copied fdvi.prg.bz2 from beta2 sources to files directory. Look at
attached ebuild.

header manipulation

Just for completness.
