/* This is the wrapper program for LyX on Win32. Using this
 * wrapper program no DOS window will be present running LyX.
 * The bad side of this: no error output could be seen ;-)
 *
 * compile this sourec with following options set:
 *
 *    gcc lyxwin32.c -O2 -o lyxwin32 -static -Wall -Wno-format \
 *                   -Wstrict-prototypes -Wmissing-prototypes \
