"""distutils.emxccompiler

Provides the EMXCCompiler class, a subclass of UnixCCompiler that
handles the EMX port of the GNU C compiler to OS/2.
"""

# issues:
#
# * OS/2 insists that DLLs can have names no longer than 8 characters
#   We put export_symbols in a def-file, as though the DLL can have
#   an arbitrary length name, but truncate the output filename.
#
# * only use OMF objects and use LINK386 as the linker (-Zomf)
#
# * always build for multithreading (-Zmt) as the accompanying OS/2 port
#   of Python is only distributed with threads enabled.
#
# tested configurations:
#
# * EMX gcc 2.81/EMX 0.9d fix03
