error: redefinition of `struct random_data'

[Sam Steingold]

All of a sudden (after the 27-Sep-10 sync with gnulib) I am getting this error 
when compiling gllib in the regexp clisp module on mingw and cygwin:
gcc -mno-cygwin -DHAVE_CONFIG_H -I. -I/.../current/modules/regexp/gllib -I..

In file included from /.../current/modules/regexp/gllib/malloc.c:

indeed, I have stdlib.h both in gllib and regexp/gllib.
what has happened?
thanks.
Sam.
