Tested on AIX 5.1 with FLTK 1.4 git revision b3b0512.
Compiler: GCC 3.4 (supports C99, but the system libc only has partial support).

The AIX mount point detection code is broken in FLTK 1.4:
The working FLTK 1.3 code is in "Fl_File_Browser.cxx" and activated by "defined(_AIX)".
It used a C90 style for-loop and with the comma two existing variables are initialized at the beginning.
In FLTK 1.4 this was changed to C99 style and the comma now has different semantics (defines two variables of type "int").

This patch should fix the problem:
patch_src_drivers_Unix_Fl_Unix_System_Driver.cxx.txt
With the patch the file "Fl_Unix_System_Driver.cxx" can be compiled.

I have not tested the fixed code yet, because the AIX 5.1 system libc does not provide the C99 "lround()" function.
As discussed with Albrecht, C90 is out of scope for FLTK 1.4, therefore I propose no patch for this problem.

At the weekend I can patch in a local lround() replacement to verify that Fl_File_Browser works as expected.
