Please describe the problem:
Fortran is a case-insensitive language; however, variables are not parsed in a case-insensitive manner in doxygen.

Steps to reproduce:
!Example code
!! @param d parameter
subroutine f(d)
integer :: D
end subroutine

Actual results:
With all warnings turned on, doxygen generates the following warnings:

Warning: argument `d' of command @param is not found in the argument list of f(integer D)
Warning: The following parameters of f(integer D) are not documented:
parameter D

However, doxygen still generates useful documentation:
subroutine f (d)
Function Documentation
subroutine f (integer D)

d da

Expected results:
doxygen should be able to figure out that d and D are the same variable

Does this happen every time?

Other information:
Similar problems are generated by the following codes:

!Example code 2
!! @param D parameter
subroutine f(d)
integer :: D
end subroutine

!Example code 3
!! @param D parameter
subroutine f(d)
integer :: d
end subroutine

Still present in 1.7.2 (r747).

Check Fortran arguments case insensetive

Fortran is a case insensitive language. When checking Fortran arguments whether or not Fortran arguments are documented this should be done in a case insensitive manner.

Confirmed. Should be fixed in the next subversion update.

This bug was previously marked ASSIGNED, which means it should be fixed in
doxygen version 1.7.5. Please verify if this is indeed the case. Reopen the
bug if you think it is not fixed and please include any additional information
that you think can be relevant.

Is there also a patch for case insensitive subroutine and function names?
In 1.8 function and subroutine names are still case sensitive.
