[geos-devel] MinGW build of Geos on Win7

[Theuns Heydenrych]

What i have figured out so far is to list the default search path for gcc
in MinGW is to issue the command
gcc -### -o foo foo.c

This will produce the following:
$ gcc -### -o foo foo.c > /c/dev/gcc.txt
gcc.exe: error: foo.c: No such file or directory
Using built-in specs.
COLLECT_GCC=c:\Tools\MinGW\bin\gcc.exe

Thread model: posix

So there right at the end is the "offending" path, some script that should
extract the -L paths, is bringing the ' character in, at the end of the
line.
No where that script is and how to fix it i dont know.

Any suggestions?
