The changes mostly revolve around:
- Type changes and casts to make the picky C-compiler happy
- Fixed bug in XmxExtractToken where it would not zero out bits 16-31 on a non-32-bit system
- Added back old getline implementation as its missing on UNICOS
- Added some missing typedefs and conditional directives to turn on the relevant code pieces for UNICOS
The code uses some constructs that cause compilers to spit out warnings. As
they do no harm, one should be able to turn off such warnings and enable others
if needed.
Some functions that ought to return a value call return without any value. This
commit adds a dummy value to each of those returns so that clang stops
complaining.
The source code for handling images has a double free problem. Recent versions
of the GNU libc have a mechanism to automagically abort the program in such a
case. This causes Mosaic to crash if images are displayed.
I work around this issue by turning of automatical program abortion with a call
to mallopt().
