Nasty Bug in MinGW

[Gabor Grothendieck]

Just thought I would ponit out this nasty bug involving std::string with g++ on MinGW under Windows to save anyone else who runs into it.  One does not usually expect such widely used tools to be the problem but that's the case here:

Thanks. Hopefully, the compiler toolchain will eventually get updated
for Windows, but it seems like R Core is comfortable with the current
state of affairs for now.

Conceptually they are not opposed to modernize the toolchain. The first step is for us to prove that we can build R from source with a more recent gcc build.

Note that there is a hack mentioned at the link I sent that will fix this problem even in the version of gcc that is being used for R with Windows now.  Applying that could be a first step and that would not involve upgrading gcc itself..
