Windows 7 64-bit, 64-bit matlab, 64-bit gcc is installed, gcc is listed as compatible on the linked page:

>> which gcc
'gcc' not found.

Please choose your compiler for building MEX-files: 

Would you like mex to locate installed compilers [y]/n? y

No supported SDK or compiler was found on this computer.

gcc and mingw are not listed for R2011a. You are possibly looking at the R2016a documentation.

That must be it; I guess the URL is forwarded now since R2011a is so old. I'll have to update I guess. Thanks for pointing that out.

The URL forwards to the PDF http://www.mathworks.com/support/sysreq/files/SystemRequirements-Release2011a_SupportedCompilers.pdf which lists lcc and various Microsoft VS and Intel compilers, and Open Watcom (which is not gcc or mingw)
