[tex-live] [issue + suggested fix] Building dvisvgm on Windows --- MinGW64/MSYS64 (via TeX Live)

Hello Martin

Firstly, thank you for writing dvisvgm --- and the latest update
(dvisvgm-1.13) to include XeTeX XDV format 6 DVI

I have experienced a problem building dvisvgm-1.13 from the latest TeX
Live sources (error dump below)
-- using MinGW64/MSYS64 on Windows 7

The problem seems to be caused by the file Process.h included with
dvisvgm: it clashes with a similarly named file
process.h (lower case p) that is included with the MinGW64 distribution.

However, the fix (hack) I used is simple: I just renamed your Process.h
to Process2.h and dvisvgm-1.13 built fine.
(of course there may be better solutions but this worked for me)

I grepped for Process.h and replaced it with Process2.h in the following
dvisvgm files:

TOTAL:    4 matches in 4 files  (215 other files without matches are not
listed)

1 match in ..\texk\dvisvgm-src\src\FileFinder.cpp
      line 45  #include "Process2.h"
1 match in ..\texk\dvisvgm\dvisvgm-src\src\Makefile.am
     line 142      Process2.h \
1 match in ..\texk\dvisvgm\dvisvgm-src\src\MetafontWrapper.cpp
      line 30  #include "Process2.h"
1 match in ..\texk\dvisvgm\dvisvgm-src\src\Process.cpp
      34  #include "Process2.h"

As noted, after renaming Process.h dvisvgm 1.13 compiled perfectly under
TeX Live.

Warm wishes
Graham
