Re: [PATCH] gnu: doxygen: Use sh from the store.

[Danny Milosavljevic]

Thanks for the patch! Looks good to me.

In any case, if we search for "portable_system", we find that there are lots of 
other things that don't use in-store names:

./cite.cpp:  if ((exitCode=portable_system("perl","\""+bib2xhtmlFile+"\" 
"+bibOutputFiles+" \""+
./dia.cpp:  if ((exitCode=portable_system(diaExe,diaArgs,FALSE))!=0) // from 
config
./dia.cpp:    if (portable_system("epstopdf",epstopdfArgs)!=0)
./diagram.cpp:    if (portable_system("epstopdf",epstopdfArgs)!=0)
./docparser.cpp:      if (portable_system("epstopdf",epstopdfArgs)!=0)
./dot.cpp:    if ((exitCode=portable_system(m_dotExe.data(),dotArgs,FALSE))!=0) 
// from config
./dot.cpp:      if 
((exitCode=portable_system(m_dotExe.data(),dotArgs,FALSE))!=0) // from config
./dot.cpp:  if (!m_postCmd.isEmpty() && 
portable_system(m_postCmd.data(),m_postArgs.data())!=0) // seems to be not set 
anywhere
./doxygen.cpp:  if (portable_system(Config_getString("HHC_LOCATION"), 
"index.hhp", Debug::isFlagSet(Debug::ExtCmd))) // from config
./doxygen.cpp:    if (portable_system(Config_getString("QHG_LOCATION"), 
args.data(), FALSE)) // from config
./formula.cpp:    if (portable_system(latexCmd,"_formulas.tex")!=0) // from 
config
./formula.cpp:      if (portable_system("dvips",dviArgs)!=0)
./formula.cpp:      if 
(portable_system(portable_ghostScriptCommand(),gsArgs)!=0) // 
portable_ghostScriptCommand body hardcodes executable name
./htags.cpp:  bool result=portable_system("htags",commandLine,FALSE)==0;
./msc.cpp:  if ((exitCode=portable_system(mscExe,mscArgs,FALSE))!=0) // from 
config
./msc.cpp:    if (portable_system("epstopdf",epstopdfArgs)!=0)
./msc.cpp:  if ((exitCode=portable_system(mscExe,mscArgs,FALSE))!=0) // from 
config
./plantuml.cpp:  if ((exitCode=portable_system(pumlExe,pumlArgs,TRUE))!=0) // 
java, hardcoded
./plantuml.cpp:    if ((exitCode=portable_system("epstopdf",epstopdfArgs))!=0)
./portable.cpp:int portable_system(const char *command,const char *args,bool 
commandHasConsole) // should have argument list, not huge string
./portable.h:int            portable_system(const char *command,const char 
*args,bool commandHasConsole=TRUE);
./vhdldocgen.cpp:    if (portable_system("dot",vlargs)!=0)
./vhdldocgen.cpp:  if (portable_system("dot",vlargs)!=0)

Aaaah found sprintf without max length specifier. 

Dear god is doxygen unsafe. I should refrain from reading the source code of 
some popular packages - it doesn't end well.

If someone is motivated, could also fix the above executable names later.
