[Discuss-gnuradio] compile errors with gcc-4.4

[ematlis]

Hi all-

I just installed Fedora 11 x86_64 which features gcc-4.4.  I get compile 
errors such as:

"gr_fft_filter_ccc.cc: In member function ‘void 
gr_fft_filter_ccc::compute_sizes(int)’:
gr_fft_filter_ccc.cc:133: error: ‘stderr’ was not declared in this scope
gr_fft_filter_ccc.cc:134: error: ‘fprintf’ was not declared in this scope"

I found this post online at 
http://osdir.com/ml/debian-bugs-dist/2009-04/msg09184.html

"Your package fails to build with GCC 4.4, which has cleaned up some more
C++ headers. You always have to #include headers directly and cannot
rely for things to be included indirectly."

The patch to fix the problem was to explicitly add cstdio include 
statements.

Taking that as a clue, I found that if I add "#include <cstdio>" to 
gr_fft_filter_ccc.cc that fixes the problem, however there are other files 
which also appear to need the same fix.  Perhaps somebody can look into 
this?  The problem appears on subversions 10991 and 11181.

thanks,
eric
