build error on xlstool.c on cygwin with gcc 4.9.3 (static declaration of ‘asprintf’ follows non-static declaration)

[fsbooks]

I get the same error with the development code.

In cygwin, I have installed the following packages if it makes a difference:

10k 2015/02/20 C:\cygwin\bin\cygasprintf-0.dll
libasprintf-devel 0.19.4-1 OK
libasprintf0 0.19.4-1 OK

Here is the text of the cran build:
