Hi all,

If I add TDCONNEXION to configure.options when compiling VMD 1.9.3a7, it adds -fpascal-strings to the INCDIRS in the Makefile. At least on the Ubuntu system I'm currently on, this immediately leads to a crash:

Compiling OpenGLExtensions.C --> OpenGLExtensions.o ...
g++: error: unrecognized command line option '-fpascal-strings'
make: *** [OpenGLExtensions.o] Error 1

>From the limited information I could find on this flag from Google, I gather it's only necessary for MacOS. Is it safe to just remove it?
