Got the latest sources from git, edit build-linux-double.sh then run it, 
and I get this:

System platform is 'linux'.
Using options from 'custom.py.'
Build platform is 'linux'.
SCons tools on this platform:  ['default', 'gnulink', 'gcc', 'g++', 
'gfortran', 'gas', 'ar', 'filesystem', 'm4', 'lex', 'yacc', 'rpcgen', 
'jar', 'javac', 'javah', 'rmic', 'tar', 'zip']
Checking for C header file libintl.h... yes
CONFIGURATION DECISION: Using GNU gettext scheme
CONFIGURATION DECISION: Using double-precision floating point for audio 
samples.
Checking for C header file stdio.h... no
  *** Failed to compile a simple test program. The compiler is
  *** possibly not set up correctly, or is used with invalid flags.
  *** Check config.log to find out more about the error.

My build-linux-double.sh is here: http://paste.lisp.org/display/136087
custom.py is here: http://paste.lisp.org/display/136086

I recently upgraded scons to 2.3.0 but I still get this. I can compile 
other stuff perfectly fine (just compiled mplayer, for example).

I'm sure I'm missing something super obvious. I was getting different 
error messages before.

Try to check what made the test fail by looking at config.log, it often helps. It could be a simple missing header or something.
One thing that sometimes fails it is the lack of gettext headers, which you could bypass by saying useGettext=0.
