[Bug c/32692] New: Inconsistent warning/error with static and non-static declarations

["sirl at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

The attached testcase just produces warning or errors (depending on gcc
version) for func1, func3 and func5:

testwarning.c:5: error: static declaration of ?func1? follows non-static
declaration
testwarning.c:3: error: previous declaration of ?func1? was here
testwarning.c:25: error: static declaration of ?func3? follows non-static
declaration
testwarning.c:23: error: previous declaration of ?func3? was here
testwarning.c:46: error: static declaration of ?func5? follows non-static
declaration
testwarning.c:43: error: previous declaration of ?func5? was here

I'm not sure about any C standard implications here, but now that 'static
follows non-static' is an error in newer gcc, I believe the other way round
deserves at least a warning to. Noticed this while compiling source code with
HP's A.10.32.03 compiler, which warns about all 6 functions on the testcase
like this:
cc: "testwarning.c", line 53: warning 562: Redeclaration of "func6" with a
different storage class specifier: "func6" will have internal linkage.

Hope this helps,
Franz
