Another option would be to replace #if ENABLE_NLS by #if defined(ENABLE_NLS)

I know the C compiler short-circuits &&, if the preprocessor does also
then this looks like the best solution. If not, then nested #if.
Yes the preprocessor also short-circuits (I tested a small example to be
sure, with gcc 4.1 and gcc 4.4). So the automatic replacement command
becomes:
find . -name '*.[ch]' -exec sed -i -e 's, ENABLE_NLS,
(defined(ENABLE_NLS) \&\& ENABLE_NLS),g' '{}' ';'

p.s. By the way, this kind of contruct appears in the autoconf manual
for a similar problem (middle of page):
