Initial Comment:
Hi Lxr folks!

I'm running genxref from the Debian unstable 0.3-2 
version of lxr and I got some "stray ifdef" that
does not look like bad ifdef's in the code. For 
example if I run genxref on this _C++_ program: 

#if 1
//*
#endif
/**/

Then the program thinks the #endif is in a C style 
comment and ignore it!

The problem seems to disappera if I change the 
genxref code lines:

 	# Remove comments.
	$contents =~ s/\/\*(.*?)\*\//&wash($1)/ges;
	$contents =~ s/\/\/[^\n]*//g; # C++

to 

 	# Remove comments.
	$contents =~ s/\/\/[^\n]*//g; # C++
	$contents =~ s/\/\*(.*?)\*\//&wash($1)/ges;

i.e. checks for C++ comments beore C comments.

Best regards
/Anders E Larsson
