[libmicrohttpd] 0.9.32 configure --disable-https; -Wsign-compare warnings

[Дилян Палаузов]

Hello,

when libmicrohttpd0932 is configured with --disable-https, the macro 
HTTPS_SUPPORT is undefined, and  struct MHD_Connection, defined in 
src/microhttpd/internal.h, does not contain the suspended and resuming 
fields.

Then src/microhttpd/connection.c : cleanup_connection : lines 2082-2094, 
does not compile, as it tries to access 
MHD_Connection.suspended/resuming, even when HTTPS_SUPPORT is undefined.

In addition, my compiler gcc (GCC) 4.7.4 20131123 (prerelease) warns about:

connection.c: In function ‘try_ready_normal_body’:
connection.c:355:42: warning: comparison between signed and unsigned 
integer expressions [-Wsign-compare]
connection.c:356:43: warning: comparison between signed and unsigned 
integer expressions [-Wsign-compare]
connection.c:362:44: warning: comparison between signed and unsigned 
integer expressions [-Wsign-compare]
connection.c: In function ‘try_ready_chunked_body’:
connection.c:429:15: warning: comparison between signed and unsigned

connection.c:446:41: warning: comparison between signed and unsigned 
integer expressions [-Wsign-compare]
connection.c:454:42: warning: comparison between signed and unsigned 
integer expressions [-Wsign-compare]

I use CFLAGS='-pipe -O3 -flto  -Wl,-S -Wl,--hash-style=gnu -Wl,-O1 
-Wl,-z,relro -Wall -Wextra' in config.site .

Kind regards
