I have been having a problem getting Inline to compile my code after a
move from version 0.47 to version 0.50. I have the following set up in
my source:

use Inline
  C        => "$src_file",
  VERSION  => '0.01',
  ENABLE   => 'AUTOWRAP',
  INC      => "-I$src_dir/src -I$src_dir/easel",
  LIBS     => "-L$src_dir/easel -L$src_dir/src -lhmmer -leasel",
  TYPEMAPS => [$typemaps],
  NAME     => 'Bio::HMM::Logo';

When I run make using version 0.47 everything compiles and the cc line
looks like this:

cc -c  -I/opt/src/Bio-HMM-Logo-0.01 -I/opt/src/Bio-HMM-Logo-0.01/src/src
-I/opt/src/Bio-HMM-Logo-0.01/src/easel -fno-strict-aliasing -pipe
-fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS=64 
-O2   -DVERSION=\"0.01\" -DXS_VERSION=\"0.01\" -fPIC
"-I/opt/lib/perl5/5.12.2/x86_64-linux/CORE"   Logo.c

When I run it using version 0.50 it fails and I get a slightly different
cc line:

cc -c  -I"/opt/src/Bio-HMM-Logo-0.01"
"-I/opt/src/Bio-HMM-Logo-0.01/src/src
-I/opt/src/Bio-HMM-Logo-0.01/src/easel" -fno-strict-aliasing -pipe
-fstack-protector -I/usr/local/include -D_LARGEFILE_SOURCE
-D_FILE_OFFSET_BITS
=64 -O2   -DVERSION=\"0.01\" -DXS_VERSION=\"0.01\" -fPIC
"-I/opt/lib/perl5/5.12.3/x86_64-linux/CORE"   Logo.c

I looked into the source and it looks like the quote_space subroutine 
(C.pm line 84) is quoting the entire INC
line("-I/opt/src/Bio-HMM-Logo-0.01/src/src
-I/opt/src/Bio-HMM-Logo-0.01/src/easel") if I have more than one path. 

Any help fixing this in future versions would be greatly appreciated.

Thanks,

Jody
