Package: deheader
Version: 1.4-1
I discovered this issue when testing deheader on the tsdfx code base.
It claimed log10() required <math.h>, but log10() was not used in the
code. It was mentioned in a comment, similar to the example below:
% cat > x.c
int main(int argc, char *argv[]) { return 0; /* log10(SIZE_MAX) */ }
% deheader x.c
deheader: in x.c, log10() portability requires <math.h>.
deheader: saw 1 files, 0 includes, 0 removable
%
As you can see, deheader believe the log10 string is code, while it is
only a comment. I believe it should ignore the content of comments when
deciding if which header files are required.
