#14 reserved identifier violation

[Markus Elfring]

This issue corresponds to my previous "feature request".

I suggest to try the search pattern "\<(?:(?:(.*))|([A-Z]+))" on source files. Some places will be found where names begin with two underscores or an underscore and an uppercase letter.

Examples:
__EXT2READ_H
https://github.com/mregmi/ext2read/blob/master/ext2read.h#L24

__LVM_H
https://github.com/mregmi/ext2read/blob/master/lvm.h#L24

This does not fit to the expected naming conventions of the C/C++ language standard.
