Source code

In case an argument starts with a reserved word (eg argument ExternalName) Doxygen does not recognise this properly and no data type is placed in the documentation (see attachment with source code and html output)

Some small investigations lead to the fact that the lexical scanner (fortranscanner.l) does recognize the reserved word External in the argument list and does not recognizes that it is not the word ExternalName.
Changing the word to MyExetrnalName also gives the correct output, so it looks like that the end of the word is nor recognized correctly.
I have hardly any experience with lex (and yacc) but shouldn't read the line (222) with the ATTR_SPEC definition read EXTERNAL> instead of EXTERNAL for this keyword. The same accounts of course for all other reserved names.

Attribute names as start of variable names are ignored

Attribute names as start of variable names are ignored by checking the next character in the input stream.

Correction to the previous patch. The unput had some side effects on yytext.

Please ignore Comment 5 with patch, is identical to Comment 6 (connection to bugzilla was very slow)
