#1st argument, if exists and is true, means create debugging symbols (PDB file)
#the DLL that is bundled is created without debugging symbols to minimize delta
#between 2 dlls upon rebuild

#
#build API_test and rtc DLLs, 32 vs 64 is based on whatever cl.exe is found in PATH
#this .pl is basically a batch file of what the VS solution calls
#using this .pl is more likely to cause low delta DLLs since VC project
#files are messy and complicated to understand what the final CL/LINK flags
#are and the flags are likely to accidentally change in the project file
#the committed DLLs are made by running this script with VC 2003 for 32 and
#VC 2008 for 64
